Can Chickens Eat Bread? 3 Things you Should NOT Feed your Chickens

This post was most recently updated on February 2nd, 2021

Some people call chickens ‘two legged pigs’ and will feed them anything. It is actually the chickens natural behaviour to compete for fresh food and they will eat it quickly, no matter what you are feeding them. One of the most commonly asked questions in the beginner chicken world is “can chickens eat bread?” Below we look at whether chickens should eat bread, as well as many other things that you should avoid feeding your chickens.



There are some common foods that you should not be feeding your chickens. What you don’t want is for the chickens to fill up their crop with low nutrient foods, and to miss out on all the goodness of the high nutrient foods.

Can Chickens Eat Bread?

Bread is a common food for well meaning people to feed to chickens and ducks. The problem with feeding chickens bread is that it can easily form a ball in the crop which can lead to catastrophic blockages. A chicken‘s gizzard is not designed for large amounts of this kind of food.

Yeasts and sugars in the bread can ferment in the crop which increases the pH of the crop contents, if fed in too larger quantities, which changes the bacteria and other microbiome that grow in the chicken‘s gizzard and crop. This can then lead on to chronic cases of sour crop that are very hard to treat.

So, in short, no, ideally you would not feed chickens bread as it has very little nutritional value and in large quantities it can cause blockages or sour crop. Small volumes of stale bread can go to your chickens, but avoid giving them moldy bread as the mold spores can irritate their breathing passages. 

If you do decide to feed bread to your chickens, try breaking it up and soaking it with some apple cider vinegar and water overnight. This will both increase the acidity, making it easier to digest, as well as breaking up the fibres to help stop it balling up in their crop.

Ducks also should not have large volumes of bread to eat either. Small amounts of bread will not hurt a duck, but you should avoid making it the basis of their diet.

Here are 3 foods you should not be feeding your chickens

1. Milk and dairy products

Some people with an orphan baby chick mistakenly think that because baby chickens are small animals, that they need to have milk, however this is not true. Chicks should start on a specially formulated chick starter feed.

It turns out that chickens are lactose intolerant! Milk is high in protein and other minerals, but the lactose can give the birds upset stomachs.

If you do give milk products, try small amounts of cultured ones, think yogurt or cheese as they have a lot less lactose in them.

2. Porridge or oatmeal

There is nothing wrong with a small volume of porridge or oatmeal, but oats are very low in protein and fat, both of which chickens need.

However, porridge fills up a chicken‘s stomach, so they don’t have room for the high nutrient foods they need to be eating.

Oats have virtually no vitamin A, D or E and high in beta glucans that birds cannot digest. Too many beta glucans will form a sludge in the gut, causing blockages.

Commercial chicken feed does contain some oats usually as a bulking agent, but they are whole, uncooked oats that are crushed not cooked.

3. Raw Eggs

You should not feed your backyard chicken eggs back to your flock. Some people feed back the egg shells for calcium. However, to be safe you are better off using oyster shell grits as a calcium source.

This is for two reasons.

1 – It can encourage the chickens to seek out and eat their own eggs.

2 – Chickens can carry salmonella, raw eggs from contaminated chickens will spread the disease amongst your flock.

If you do want to feed your chickens eggs, you can scramble the eggs and cook them and heat the shells in a hot oven for at least 20 minutes to kill any bugs. Then you can crush the egg shells so they are unrecognizable to the chickens in the coop.

Here are some other foods that you should avoid giving your chickens:

  • Onions and garlic can give the eggs an off taste
  • Fresh potato peels, especially those tinged green, contain a toxin called solanine.
  • Avocado pits and skins both include a potentially fatal toxin called persin.
  • Avoid feeding your flock rhubarb and citrus.
  • Undercooked or dried beans contain an avian toxin called hemaglutin.

Generally speaking, a well fed chicken will not attempt to eat toxic foods as their only taste buds are ones for bitter food, bitter foods are usually toxic, and they are quite good at not eating them!

The best advice is to feed a balanced, commercial feed first, then let the chickens eat their other food, treats or forage later in the day. This will ensure they are getting all the nutrition they need for growth and egg production.

Commonly asked questions from a chicken keeper about what you can feed chickens

Can chickens eat grapes?

Yes, chickens enjoy eating grapes and if you throw them to your flock you will find that they rush after them and argue over them. Grapes are very sweet and mostly contain water and sugar so they should be kept as a special treat for your flock rather than a basis of a nutritionally complete chicken feed.

Can chickens eat uncooked rice

Uncooked rice is hard to digest and it will expand and absorb quite a quantity of water in the chickens gullet. Rice flour will congeal together and can cause a blockage. Rice is low in nutritional value, and high in simple starches so it is not an ideal chicken food. If you are going to feed your chickens rice, it is best cooked, or at least crushed (but not powdered) and mixed in with their other grains to dilute it.

You can feed your chickens small volumes of cooked rice, this is unlikely to cause any issues in your flock. But it is best to keep this as an occasional food, and give it after they have eaten their usual grain feed so that you know they are getting their full nutrition. 

Can chickens have bananas

Chickens enjoy eating bananas and they will even eat the banana peels. Very nutritious, they are high in vitamins B6, C & A also contains niacin, iron and magnesium plus other trace elements.

Can chickens eat chocolate

No, chickens should not eat chocolate or coffee. There are toxic substances in chocolate called theobromine and caffeine. The higher the cocoa content and the darker the chocolate, the more theobromine it contains and the more dangerous it is to your chickens.

Can chickens eat strawberries

Strawberries are healthy and nutritious for chickens to eat on occasion. Strawberries are low in sugar and high in nutrients. Chickens will also eat the leaves of strawberry plants, so if you have free ranging chickens it is best to fence off your garden if you want your strawberry plants to survive.

Can chickens eat broccoli

Chickens enjoy eating both the heads (florets) of broccoli as well as the leaves. The stems of the broccoli plant are too hard for your hens to peck at unless they are cooked. All parts of the broccoli plant are healthy and nutritious for chickens to eat.

Can chickens eat cabbage

Cabbage makes a wonderful distraction for bored chickens. Hang a head of cabbage from a rope in the chicken coop and watch the chickens peck and play with the cabbage while eating it all. Cabbage is healthy for chickens and they enjoy all parts of it raw or cooked, only the hardest part of the stem will be left. All varieties of cabbage are fine, Chinese cabbage, red cabbage, pak choi and normal green cabbage.

Can chickens eat raisins

In small volumes, the occasional raisin is ok for your chickens to eat. However, large volumes of raisins can cause renal failure in many animals, chickens included. The high level of sugar in raisins is not good for the chickens either. 

Can chickens eat oatmeal
