Yes, chickens can eat frozen peas, straight from the bag or thawed. A frozen pea is just a garden pea that was shelled, blanched for a minute or two and frozen. None of the guides I read asks you to cook peas for hens. Feedipedia, the big animal feed database, even says the dry peas grown for livestock “can be fed raw or processed.” What you do need to watch is how many. About a tablespoon and a half is a hen’s whole treat allowance for the day, so peas share that space with every other extra she gets.
I rewrote this page from 19 sources, and you’ll find every one listed at the bottom. USDA’s FoodData Central gave me the numbers for each kind of pea, from raw to canned. A 2007 review from UC Davis covers what freezing really does to vitamins. Illinois Extension and the National Center for Home Food Preservation explain how peas get frozen in the first place. The hot-weather advice comes from extension services in Arizona and Mississippi, with water numbers from Minnesota. Colorado State and Alabama set the treat limits, and the Merck Veterinary Manual has the salt numbers. Where the advice is my own reasoning, I’ll tell you.
The short version.
- Frozen or thawed, both are fine. You don’t need to cook them.
- About a tablespoon and a half a hen a day. That’s all of her treats together, not just the peas.
- On a hot day they’re a cool snack, not a cooling plan. Shade and cool water do the real work.
- Plain bags only. Skip peas with butter or sauce.
- Pick up any thawed peas your hens leave behind.
- Canned peas are OK in the same small amount. Frozen peas or a no-salt-added can carry the least salt.
- Chicks start on chick starter alone.
- Sweet peas, the garden flower, aren’t peas at all. Keep your hens out of them.
Frozen Peas Are Garden Peas
A bag of frozen peas is garden peas picked young. Illinois Extension puts it plainly: “Green garden peas are legumes just like dried peas, except they are eaten at the immature stage.” Feedipedia says garden peas are “harvested while still immature” and then “marketed fresh, canned, or frozen.” The dry field peas in some poultry feeds come from the same plant. Feedipedia says the two used to be counted as separate species, and now they’re seen as varieties of one, Pisum sativum.
That’s good news for your flock, because field peas have been studied as chicken feed for years. Feedipedia says “Peas are a good source of protein and energy for poultry.” The catch comes right after: “However, they are deficient in sulfur-containing amino-acids”. Broiler trials have fed peas at 20% of the diet and more, and Feedipedia says “For laying hens, similar inclusion rates are suggested”. But that’s dry peas worked into a balanced ration by a feed mill. It isn’t a bowl of frozen peas in place of her feed.
If you’ve read our page on black-eyed peas, you might wonder about raw peas. Black-eyed peas are cowpeas, a different plant, and they need cooking. Garden peas are easier on a bird. Feedipedia calls trypsin inhibitors “the main antinutritional factor in peas,” but it also says peas are “one of the grain legumes with the least trypsin inhibitor content.” Raw soybeans carry about 8 times as much. And every frozen pea has already had a short dip in boiling water at the plant. So I don’t see a reason to cook them for your hens.
You can just pour out a little and let your flock go to work.
What the Freezer Does
That dip is called blanching. The National Center for Home Food Preservation blanches green peas for a minute and a half before freezing them, and it says blanching “helps retard loss of vitamins.” Then the peas go into the freezer.
The old version of this page said freezing ruins a pea’s vitamins. USDA’s numbers don’t back that up. Per 100 grams, raw green peas have 5.42 grams of protein and 5.7 grams of fiber. Frozen peas have 5.22 grams of protein and 4.5 grams of fiber. The big drop is vitamin C, from 40 milligrams in raw peas to 18 in frozen ones.
Fresh peas lose that vitamin fast anyway. The UC Davis review, by Joy Rickman and two colleagues, says green peas were found to lose 51.5% of their vitamin C in the first day or two after picking. It puts the losses from freezing at about 50% on average. Over a year in the freezer, it says green peas “suffered minimal losses.” One study it cites found that cooked frozen peas had as much vitamin C as cooked fresh ones, or more.
And here’s the part that matters for a hen. She doesn’t need vitamin C from her food at all. University of Maryland Extension says “Unlike humans, poultry can synthesize vitamin C,” so it isn’t something your hens need in their diet.
The one vitamin the freezer really cuts is one your hens make for themselves.
The old page also said freezing turns starch into sugar. It’s the other way around, and it happens before the freezer. Illinois says a fresh pea’s sugar “quickly begins to turn to starch even while under refrigeration,” with up to 40% of it changing in a few hours. USDA lists 4.99 grams of sucrose in raw peas and 4.6 in frozen ones.
So no, the peas in your freezer aren’t sweeter than fresh ones.
A Hen’s Share
Peas are a treat, so they live inside the treat limit. Colorado State’s extension says “Treats should make up no more than 10% of their daily diet.” Alabama’s says a laying hen eats between 100 and 150 grams of feed a day. By my math, that leaves 10 to 15 grams of treats a hen a day, counting every extra you give her.
USDA weighs a cup of frozen peas at 134 grams, so a tablespoon is about 8.4 grams. That puts a hen’s whole allowance at about 1¼ to 1¾ tablespoons. Call it a tablespoon and a half. For six hens, that’s 9 tablespoons, a little over half a cup. If your flock also got kitchen scraps or scratch that day, cut the peas back.
It sounds stingy, I know. Here’s why you should stick to it anyway.
It comes down to protein. Alabama says layer feed should run 16% protein or more. Frozen peas are 5.22% protein, because they’re about 80% water. By my math, a hen’s 12.5 grams of peas holds about 0.65 grams of protein, while the same weight of layer feed holds about 2 grams. Alabama compares treats to ice cream. Offer kids ice cream at every meal and they’ll eat it with gusto. Hens do the same thing, and Alabama says birds “will fill up on these incomplete feeds and not consume enough of the complete feed to sustain egg production or growth.” UC Davis says it shorter: “treat the scraps like a treat not like the main course.”
Colorado State adds a rule I like: “Do not feed more than can be consumed in 5 – 10 minutes to not attract nuisance animals.” So toss the peas where your hens will find them all. A pea lost in the bedding is a snack for whatever comes around the coop at night. Our Rhode Island Red feeding guide covers the layer feed that should fill the rest of her day.
Straight From the Freezer on a Hot Day
Frozen peas get passed around as a summer treat, and two extension services back the idea, carefully. Ashley Wright of University of Arizona Extension says a hen eats less in a heat wave: “a hot chicken will have a decreased appetite. For this reason, it’s important to limit treats and extras (especially scratch grains).” What she suggests instead is “frozen watermelon or fruits/veggies chopped and frozen into a block.” Those keep hens “cool and busy without excessively filling them up.”
Mississippi State’s extension, passing on tips from its poultry specialist Jessica Wells, gives the same warning: “Frozen treats can also help keep chickens cool but be cautious with these.” When it’s hot, “chickens will choose to eat less,” so you want to be sure they’re still eating their regular feed. It also suggests “Freezing cut-up fruits and vegetables in water-filled ice trays.” Peas fit that idea well. A few in each cube of a tray makes a hen’s share easy to count, and that part’s my own idea.
Treats come after the basics, though. University of Minnesota Extension says that during heat stress, birds drink 2 to 4 times their normal amount of water. It calls more ventilation to carry heat away “your first priority.” So keep shade over the run and air moving through the coop, with plenty of cool water out.
On the water itself, two of the guides disagree. Arizona says to “Add ice cubes, ice blocks, or frozen water bottles if needed to keep water cool.” Mississippi State says “Do not add ice.” Both want water that’s fresh and cool, so I’d keep the waterer in the shade and refill it often. And if you want the arithmetic on how much water a treat really carries, our page on watermelon for chickens works it out.
Thawed Peas and Old Bags
Thawed peas are just as fine as frozen ones. Illinois, writing for cooks, says “Fresh frozen peas do not need to be cooked upon thawing.” What changes once they thaw is how long you can leave them out.
The USDA’s Food Safety and Inspection Service, writing about our own food, says “Food stored constantly at 0 °F will always be safe.” But freezing only makes germs go dormant. Once food thaws, FSIS says, those microbes “can again become active.” So thaw just your flock’s share, and don’t let a dish of soft peas sit in a warm run all afternoon. Whatever your hens leave after 5 or 10 minutes, pick up.
You’ll learn fast how much your flock actually cleans up.
An old bag with frosty, dry patches is a different story. That’s freezer burn, and FSIS says “Freezer burn does not make food unsafe, merely dry in spots.” Its line on long storage is short: “Freezer storage is for quality only.” So a bag you forgot at the back of the freezer is still fine to share, as long as it stayed frozen.
Read the bag first, though. Some frozen peas come with butter or a sauce. Colorado State says to make sure treats “are not salty,” and the Merck Veterinary Manual warns that fat scraps “promote the development of fatty liver.” The bag to share is the one with nothing but peas on the label.
Chicks and Peas
Chicks need a slower start. Gail Damerow, writing for Cackle Hatchery, says “Feed only starter ration for at least the first two weeks.” After that, treats shouldn’t be “more than 10% of the chicks’ diet by volume.” UC Davis says chick starter “should have a protein content of approximately 20%,” and peas at about 5% protein water that down.
Cackle’s guide doesn’t name peas, but its rules fit them. “Never feed chicks foods that are flavored with sugar, salt or other seasoning, butter, or oil.” That’s the plain-bag rule again. “Chop everything into chick-size bits to prevent choking.” A whole pea is a big bite for a small chick, so I’d thaw the peas and chop or mash them. And Cackle says to “remove any uneaten leftovers,” since moist food in a warm brooder can grow mold and bacteria.
One more line from Cackle: “when they start eating anything fibrous, they need grit.” So once peas go into the brooder, chick grit goes in too. Our page on when baby chicks can eat fruits and veggies covers the rest of the chick treat list.
Canned Peas and Salt
Canned peas work too, but they bring salt along. USDA’s sodium numbers per 100 grams tell the story. Raw peas have 5 milligrams, and frozen peas have 108. A regular can, counting its liquid, has 185. Drained canned peas have 273, and drained and rinsed ones have 231. Peas from a no-salt-added can, drained, have just 2.
To compare that with a hen’s feed, I turned sodium into salt, which weighs about 2.54 times the sodium. By my math, frozen peas come out around 0.27% salt. Drained canned peas are about 0.69%, and rinsing brings them to about 0.59%. The Merck Veterinary Manual says adding “0.5% salt (NaCl) to the ration of chickens and turkeys is recommended,” and that “amounts > 2% are usually considered dangerous.” So even drained canned peas sit well under Merck’s danger line. Still, Colorado State’s “Make sure they are not salty” points the same way as the numbers. Frozen peas or a no-salt-added can are the better pick.
Rinsing helps less than you’d think. USDA’s two entries show about 15% less sodium after a rinse, by my math, and since they’re two different samples, that’s a rough figure. Canned peas also carry less protein, 3.01 grams per 100 for a regular can with its liquid. They’re the lowest in vitamin C too, which, as we saw, a hen doesn’t need from her food. But the old claim that canning is gentler than freezing doesn’t hold up. The UC Davis review says canning loses more than 60% of the vitamin C on average, against about 50% for freezing.
Pea Plants and Sweet Peas
If you grow peas, your hens will find the vines sooner or later. Feedipedia has a separate sheet on pea forage, the stems and leaves, including the pea straw left after harvest. It covers ruminants and pigs. It covers rabbits and horses too, and says pea vines “were found to have a high nutritive value for rabbits.” Its warnings are about tannins in some colored-flower varieties and saponins in the straw. Moldy pea straw, it says, “should not be given to animals.”
There’s no poultry part on that sheet. None of the other sources I read tested hens on pea vines either, so I can’t point you to a study. My own read is that it’s the same plant as the peas, and other livestock eat the vines. A hen pecking at your pea patch isn’t something I’d lose sleep over. A fence is still the best way to keep the peas for yourself. That’s my reasoning, not a study.
Sweet peas are another matter. The flower people grow along fences isn’t a garden pea at all. It’s a Lathyrus. The ASPCA’s plant list files its sweet pea entry under Lathyrus latifolius, also called perennial pea or everlasting pea, and marks it toxic to horses. Its list of signs runs from weakness and pacing to seizures. Feedipedia, writing about a related plant, says “Many Lathyrus species are implicated in a paralysis of humans and animals known as lathyrism.” Neither source tested chickens.
Still, if you grow sweet peas, I’d keep your hens out of that bed and never toss them the seed pods.
For the rest of the legume family, our page on dried peas and lentils for chickens uses the same treat math. Black-eyed peas need cooking first, and that page explains why. Our list of what you shouldn’t feed chickens covers the hard noes. And for a quick answer on any other food, try our Can Chickens Eat It? food checker.

Peas in ice trays, chopping them for chicks and keeping hens out of sweet peas are my reasoning, since no source I read tested any of that with peas. We aren’t vets. If a hen looks sick, call a vet who sees poultry.
