What Chickens Cannot Eat – UK Poultry Feeding Laws Explained

While chickens can eat a wide variety of foods, poultry keepers in the UK must follow strict feeding regulations designed to protect animal health and prevent disease outbreaks.

Certain foods are unsafe for chickens, and some are illegal to feed under UK law.

Understanding these rules is an important part of responsible poultry keeping.

This guide explains which foods should never be fed to chickens and the legal feeding rules that apply in the UK.

The Most Important Rule in the UK

In the UK it is illegal to feed poultry kitchen scraps or catering waste.

This includes:

• Food that has been inside your kitchen
• Plate leftovers
• Food prepared in a kitchen
• Food from restaurants or catering businesses
• Food that has been in contact with meat or fish

These rules apply to all poultry keepers, including people who keep a few backyard chickens.

Why These Rules Exist

These regulations exist to prevent the spread of serious animal diseases such as:

• Foot and Mouth Disease
• African Swine Fever
• Avian Influenza

Food that has passed through kitchens or food preparation areas may have been contaminated with animal products, which can carry disease.

For this reason, UK law classifies these foods as catering waste, which cannot legally be fed to poultry.

Foods That Should Never Be Fed to Chickens

Some foods may be harmful or toxic to chickens.

These include:

Chocolate

Chocolate contains theobromine, which is toxic to many animals including poultry.

Alcohol

Alcohol can be extremely harmful and should never be given to chickens.

Very Salty Foods

High salt levels can damage a chicken’s health and should be avoided.

Mouldy Food

Mouldy or spoiled food may contain toxins that can cause serious illness.

Raw Potato Peels or Green Potatoes

These may contain solanine, a natural toxin which can be harmful to chickens.

Foods That Are Illegal to Feed in the UK

Under UK regulations, poultry must not be fed catering waste.

This includes:

• Kitchen scraps
• Plate leftovers
• Restaurant food waste
• Domestic kitchen food waste
• Meat or fish scraps
• Food that has been in contact with meat or fish

Even vegetable scraps become illegal to feed once they have entered a kitchen environment.

Responsible Poultry Feeding

Responsible feeding practices help protect both your flock and the wider poultry industry.

Following UK feeding regulations helps reduce the risk of disease spreading between farms and backyard flocks.

Providing a balanced diet and following proper feeding rules supports healthy chickens and strong biosecurity standards.
