Can Chickens Eat Gourds? Squash Yes, Decorative Gourds No

Yes, chickens can eat the squash and pumpkins you’d eat yourself, as a small treat. Decorative gourds are a different story, and so is any squash that tastes bitter. Those stay out of the run.

Here’s why the word gourd trips people up. It covers the butternut on your kitchen counter and the warty little things in a fall centerpiece, and those aren’t the same food at all. Squash and gourds can make bitter compounds called cucurbitacins. And the National Capital Poison Center says squash with too much of them can “look and smell normal but taste very bitter”.

I rewrote this page from 20 sources, and they’re all listed at the bottom. The cucurbitacin facts come from poison centers in the US and Europe, a Nordic food-safety review and a chick feeding study. The gourd facts come from six university extension services. The feeding rules come from Alabama Extension, Colorado State and the Merck Veterinary Manual. Where something is my own math or my own call, I’ll say so.

The short version.

• Plain squash or pumpkin that was sold or grown to eat is fine as a small treat.
• Taste a tiny raw bit first. If it’s bitter, it goes in the trash, not the run. Cooking won’t fix it.
• Decorative gourds aren’t food. France’s food-safety agency calls the ornamental kinds toxic.
• Anything painted, waxed, shellacked or moldy stays out. That includes a jack-o’-lantern that’s started to go.
• Garden squash grown from your own saved seed can turn bitter. Buy new seed.
• A hen’s whole treat share is 10 to 15 grams a day. One cup of pumpkin cubes covers about 8 to 12 hens.

A Gourd Can Mean Two Different Things

Purdue Extension draws the line pretty clearly. “The term gourd is most correctly applied to the hard-shelled, non-edible cucurbit fruits suitable for ornaments or utensils”. Squash and pumpkins are in the same plant family, but they’re the ones grown to eat.

It gets blurry fast, though. Purdue also says “Some types are edible while young and tender”, and Arkansas Extension says “Some varieties of gourds can be eaten when immature”. Missouri Extension splits the decorative ones into two groups. The small, colorful ones are Cucurbita, the same genus as squash. The big hard-shelled ones, the kind people make into ladles and containers, are Lagenaria.

So here’s the trouble. Look at a wheelbarrow like the one in the photo above. Vermont Extension counts “warty varieties” among the decorative gourds. But Purdue says some squashes, Golden Summer crooknecks among them, are “highly attractive and useful for ornamental purposes” too. So even the warty, curved one could go either way, and I couldn’t tell you which of these were grown for the table.

Honestly, that’s the whole point of this page. When somebody asks whether hens can eat gourds, the answer depends on which gourd. And you can’t always tell by looking.

The Squash and Pumpkin You’d Eat Are a Fine Treat

This part’s easy. The squash and pumpkins sold to eat are fine for hens in small amounts. Rutgers runs a farm that takes in people’s old Halloween pumpkins. A 2023 Rutgers story says “the safe pumpkins are fed to the pigs and chickens in addition to their regular feed”.

Notice that last bit. In addition to their feed, not instead of it.

Pumpkin is mostly water. USDA’s FoodData Central puts raw pumpkin at 91.6 grams of water per 100 grams, with 1.0 gram of protein and 26 calories. Raw butternut is a little richer, at 86.4 grams of water and 45 calories.

Now compare that with what a laying hen needs. Alabama Extension’s layer diet calls for protein at “16% or more” and calcium at 3% to 4%. Raw pumpkin works out to about 1% protein, by my math (1.0 gram out of 100). So it’s a nice change for the flock, but it can’t stand in for a bag from the feed store.

The seeds are a different food. USDA lists dried pumpkin and squash seed kernels at 559 calories per 100 grams, with 49 grams of fat. By my math, that’s about 21 times the calories of the same weight of raw pumpkin flesh. We’ve got a whole page on acorn squash seeds if your hens go for those.

One catch before you hand any over, even store-bought winter squash. It gets a quick taste first. The next section is why.

Bitter Is the Warning, and You Can’t See It

Here’s the part most pages skip. The poison center explains where the bitterness comes from: “Plants produce cucurbitacin as a defense mechanism against insects and animals that feed on them”. Swiss poison center Tox Info Suisse says edible squash “have been cultivated to largely eliminate cucurbitacins”. Largely, not always.

And a bitter one doesn’t look any different. The National Capital Poison Center says these squashes “look and smell normal but taste very bitter”. France’s food-safety agency, ANSES, says cucurbitacins are “not destroyed by cooking”. Tox Info Suisse adds that they can’t be washed away either, since they’re inside the plant.

So the test is your own tongue, and it’s a good one. A Nordic review of cucurbitacins in food says “Cucurbitacins are immensely bitter”. Taste panels picked one of them up at 1 part per billion in water. The poison center’s advice for people is to “Take a very small taste of raw squash, pumpkin, zucchini, or cucumber to check if it is bitter”. If it is, “spit it out and throw it away”.

That advice was written for people. Using it for the flock is my call, and here’s why I make it. The same Nordic review says “Chickens fed cucurbitacin-containing plant material developed damage in the intestine and the liver”.

One study the review describes is a small one from the University of Khartoum, published in 1995. The researchers fed 7-day-old chicks the seed of colocynth (Citrullus colocynthis), one of the bitter cucurbits the Nordic review covers. The seed made up 2% or 10% of their diet, for 6 weeks. At 10%, the chicks’ body weights and feed efficiency were “markedly depressed”. The damage the researchers found in the intestines and livers, among other places, was “fully reversed 4 w after removal from the experimental diet”.

Two things about that. It was a lot of bitter seed, a tenth of everything they ate, for weeks. And none of my sources tested a hen on one bite of bitter zucchini. But the review is clear that chickens aren’t immune, and I’m not going to run that experiment on a laying hen.

People get sick from it too. ANSES counted 353 people in France from 2012 to 2016 who ate bitter squash or gourds, mostly with digestive symptoms, and 4% had pronounced or prolonged symptoms. Tox Info Suisse reports a 79-year-old man in Germany who died in 2015 after eating a bitter courgette (that’s a zucchini) from his own garden. That’s rare. But it happened.

One more number from ANSES. Of the bitter ones where the source was known, 54% came from home gardens and 46% were bought. So a squash from the store gets the same little taste.

My rule is simple. Anything bitter goes in the trash. Not the run, and not the compost pile your hens scratch through either.

Decorative Gourds Aren’t Food

The gourds sold every fall for the porch and the table are grown to look at, not to eat. ANSES says ornamental gourds such as colocynths, “all of which are considered toxic”, are sold “for strictly decorative uses”. It also says they’re sometimes sold in the fruit and vegetable section.

Tox Info Suisse says that’s why you’ll see ornamental pumpkins labelled “only for decoration” or “not for consumption”. The National Capital Poison Center agrees: “Decorative squashes such as colocynths are not edible since they contain high concentrations of cucurbitacin”.

Purdue lists the shapes the small decorative ones come in, Cucurbita pepo variety ovifera: “apple, pear, bell, egg, bicolor, or orange”. And here’s my honest take on the photo above. I can’t tell you whether those striped ones were grown to eat or to decorate. From a picture, neither can anybody else. So I’d go by what it was sold as, not by how it looks. If it was sold for decorating, or you just don’t know, it doesn’t go to the flock.

The big bottle gourds aren’t a treat either. They’re Lagenaria, and in some places bottle gourd juice is used as a home remedy. A 2011 report from India describes 15 patients who drank bitter bottle gourd juice. They came in with belly pain and vomiting within 15 minutes to 6 hours, and some had vomited blood. They all recovered. An older version of this page called bottle gourds a fun treat for hens, and I’ve cut that.

If a hen did get into a decorative gourd or a bitter squash, I wouldn’t wait to see how she does. None of my sources lists what cucurbitacin looks like in a backyard hen, so I won’t hand you a made-up list of signs. Call a vet who sees poultry, and bring a piece of what she ate.

Better yet, find that vet before fall decorating season. Colorado State says “Flock owners must have an identified veterinarian in their area that can diagnose and treat chickens”.

Painted, Waxed or Shellacked? It Stays Out

Then there’s what people put on gourds and pumpkins. Extension guides for curing gourds are full of finishes. Missouri says to dip or coat them in a household disinfectant, and that “A light coat of wax provides further disease protection and gives them an attractive sheen”. UConn says “Gourds may be sprayed with an acrylic resin or lacquer, waxed with floor polish, or shellacked”. LSU describes a bleach dip, and Arkansas suggests “several coats of clear shellac”.

None of that is chicken food. Vermont Extension even warns that “some decorative treatments should not be composted”. If a finish shouldn’t go in your compost, it sure shouldn’t go in your hens.

The Rutgers farm draws the same line for its pigs and chickens. It “only accepts pumpkins that are free of paint, chemicals, and mold to ensure the safety of the animals”. So a pumpkin with painted lettering like this one is out. My own rule goes one step further: if I can’t say what’s on the skin, it doesn’t go to the flock.

The Jack-o’-Lantern After Halloween

Now the big one this time of year. Rutgers asks people to bring their “festive masterpieces” to the farm instead of throwing them out, so a plain carved pumpkin can be feed. But it has to pass the same check. Rutgers says any unpainted pumpkins that are starting to mold go to the compost bin, not the animals.

Mold is the one I’d watch hardest. The Merck Veterinary Manual’s chapter on mycotoxins in poultry says “Prevention involves using feed and ingredients free of mold growth and mycotoxins”. And Jacquie Jacob’s feeding guide for small flocks warns, “Make sure that the scraps are not allowed to rot, or botulism might result”.

Here’s how I’d handle a jack-o’-lantern (these steps are my own calls, built on those rules).

• If any part is soft, slimy or fuzzy, the whole thing goes to the compost.
• If it had a candle in it, cut away the wax drips and any black soot.
• Give it the same tiny raw taste as any other squash.
• Chop it up and hand out a little at a time. Don’t toss the whole pumpkin in the run.

Saved Seed Can Turn Your Garden Squash Bitter

If you grow squash, this one’s worth knowing. ANSES explains that inedible and edible kinds can cross when they grow in the same patch or next door “and the seeds are harvested and re-sown year after year”. The result can “look exactly like edible squash, except that they have a bitter taste”.

Stress can do it too. The Pacific Northwest plant disease handbook says “Abiotic or biotic stresses, including water stress, may result in higher levels of cucurbitacins in cucurbit fruit”. It says high nitrogen can as well. Tox Info Suisse names dry, extremely hot weather.

The poison center’s garden advice is short. “Buy new seeds each year”, and “Do not plant edible and nonedible varieties of squash close to each other”. ANSES says the same thing: “Do not collect seeds from previous harvests for re-sowing”.

For a chicken keeper, I’d add two things of my own. Don’t grow decorative gourds on the run fence, and don’t hang them in the coop (an older version of this page suggested it). And if the flock gets your garden’s extra zucchini, taste each one before it goes over the fence.

How Much a Hen Gets

Now the math. Alabama Extension says a laying hen “will consume between 100 and 150 grams of feed per day”. Colorado State says “Treats should make up no more than 10% of their daily diet”. So by my math, that’s 10 to 15 grams of treats a hen a day, counting every extra she gets, not just the squash.

USDA says a cup of raw pumpkin in 1-inch cubes weighs 116 grams. So one cup is the whole treat share for about 8 to 12 hens (116 divided by 15 is 7.7, and divided by 10 it’s 11.6).

That’s how far off the old version of this page was. It said 1 to 2 cups per chicken. By my math, that’s 116 to 232 grams, more than a hen’s whole day of feed.

Calcium is where it really shows. Alabama Extension says “The eggshell is composed of around 96 percent calcium carbonate”. USDA puts raw pumpkin at 21 milligrams of calcium per 100 grams, so a 10 to 15 gram share holds about 2 to 3 milligrams. The same weight of layer feed at 3% to 4% calcium holds 300 to 600 milligrams. That’s my math. It’s the same point the Merck Veterinary Manual makes when it says “birds should receive most of their diet from a balanced, nutritionally complete ration”.

As for serving it, cut it into small pieces, or split a squash so they can get at the flesh. Then give only what they’ll clean up quickly. Colorado State says “Do not feed more than can be consumed in 5 – 10 minutes to not attract nuisance animals”. Jacob’s guide gives 20 minutes for scraps and scratch grains together. Pick up whatever’s left.

What I’d do with squash and gourds this fall.

• Feed only squash and pumpkin that was sold or grown to eat, plain.
• Taste a tiny raw piece first, and trash anything bitter.
• Keep decorative gourds out of the run and out of the coop.
• Skip anything painted, waxed, shellacked, glittered or moldy.
• Cut a clean jack-o’-lantern into pieces and hand it out a little at a time.
• Buy new squash seed each year, and keep ornamental gourds out of the vegetable patch.

Squash isn’t the only cucurbit we’ve written up. There’s watermelon, and bitter melon is a cousin with its own rules. There’s also our longer list of what not to feed chickens, and our can chickens eat it checker covers a long list of other foods.
