Can Chickens Eat Zucchini?
Safe Yes, chickens can eat zucchini, skin and seeds included, and an oversized garden zucchini split in half is one of the best free treats a flock can get.
How much zucchini can chickens have?
Treats of every kind put together should stay under about 10 percent of what a hen eats in a day. An adult laying hen eats roughly 113 g of complete feed, so that comes out around 11 g per bird per day. That is a planning figure rather than a measured limit, and it is the budget for everything the flock gets besides its feed, not an extra allowance for zucchini on its own. Six hens share about 66 g a day. Enter your own flock size:
Per bird per day11 g (0.4 oz), about 0.5 thick slices
Whole flock per day66 g (2.3 oz)
Which parts are safe
Fine to feed
- Whole fruit, any size
- Skin
- Seeds
- Flowers
- Cooked zucchini with nothing added
Keep out of the run
- Bitter-tasting zucchini (cucurbitacin)
- Zucchini bread, fritters or seasoned dishes
- Slimy or mouldy fruit
How to serve it
Split a large zucchini lengthways and leave the halves in the run; the flock hollows them out over a few hours. Slice smaller ones. Taste a sliver of any home-grown zucchini first; if it is bitter, compost it.
The gardener's treat
Anyone who grows zucchini ends up with baseball bats hidden under the leaves in August, too seedy and watery for the kitchen. They are exactly what a flock wants. Split one in half and hens spend the afternoon scooping out seeds and flesh, leaving a thin skin. It costs nothing, it keeps a bored flock busy, and there is nothing in it to worry about.
Nutritionally it is mild: 95 percent water, a little protein for a vegetable, some potassium and vitamin C, and almost no sugar. That low sugar is why zucchini is easier to be relaxed about than fruit; the only cost of overfeeding is that hens eat a bit less layer feed that day.
The bitter exception
Zucchini and other squash occasionally produce cucurbitacin, a bitter compound that the plant makes under stress or from a rogue cross-pollination. In quantity it causes vomiting and diarrhoea in people and the same digestive upset in birds. It is easy to catch: cucurbitacin tastes strongly bitter. Taste a sliver of any home-grown zucchini before giving it to the flock, and if it is bitter, bin it. Shop zucchini almost never has this problem.
Seeds, skin and flowers
All edible. The seeds of a big zucchini are a favourite and are safe raw. The skin is soft enough to eat even on large fruit. The yellow flowers are edible for hens as well as people, though they are usually worth more on your plate. Cooked zucchini is fine if it was cooked plain; fritters and zucchini bread bring salt, flour and fat.
Zucchini: nutrition per 100 g
| Nutrient | Per 100 g, raw |
|---|---|
| Calories | 17 kcal |
| Protein | 1.2 g |
| Water | 95% |
| Sugars | 2.5 g |
For comparison, layer feed is about 16 percent protein and is formulated to be the whole diet. Whatever zucchini adds, the feed still has to do the work: see the chicken feed calculator for how much a flock eats and the water calculator for how much it drinks.
How we calculate it
Planning estimate, not a measured threshold. The published guideline is that treats, scratch and scraps together stay under 10% of the daily diet; applying that to an adult laying hen's roughly 113 g of feed gives about 11 g per bird per day for all treats combined. Item counts divide that by an estimated 15 g per thick slice and round DOWN, so a shown portion never exceeds the allowance.
Based on:
- Nutrition per 100 g, raw (USDA FoodData Central)
- Scratch, grains and kitchen scraps should be provided at no more than 10 percent of the daily diet (Oklahoma State University Extension)
- Excess table scraps and greens reduce egg production; keep supplements to a small share of the diet (Poultry Extension)
- A laying hen eats about a quarter pound of feed a day; avoid high levels of human food or scraps (Penn State Extension)
Figures are typical guidelines for planning. Your birds, breed, climate, and feed will vary.
Frequently asked questions
Can chickens eat raw zucchini?
Yes. Raw, skin and seeds included, is the easiest way to feed it. Split large ones in half.
Can chickens eat zucchini seeds?
Yes. The seeds are safe and hens eat them first. Claims that they deworm chickens are not supported by evidence.
How much zucchini can chickens have?
Strictly about 11 g per bird a day, which is half a thick slice, under the 10 percent treat guideline. Because it is nearly all water and low in sugar, a shared half zucchini a few times a week is a reasonable version of that.
