Chicken Health for UK Keepers
By Kaiser Khan, EditorPublished Last updated 4 min read
Quick answer
Healthy backyard hens need secure, ventilated housing, a complete poultry feed, clean water and daily observation. In England and Wales, register even a small pet flock. Never feed household kitchen scraps. Keep a poultry vet's number ready, follow current bird-flu rules, and report suspected avian influenza immediately.
Key takeaways
- No. Household kitchen scraps and catering waste must not be fed to poultry, including backyard hens. Use a complete feed appropriate to their age and purpose, with clean water and suitable grit.
- Contact your vet and report suspected avian influenza immediately to the Animal and Plant Health Agency. It is a notifiable disease; follow official advice about movement, biosecurity and any current local control zone.

Register your birds and prepare for a vet visit
In England and Wales, you must register poultry or other captive birds with the Animal and Plant Health Agency within one month of keeping them, including a flock of fewer than 50 pet birds. Registration helps APHA contact keepers during disease outbreaks. You must confirm your details every year and tell APHA about relevant changes. Check the current registration instructions; Scotland and Northern Ireland have their own guidance.
Before illness strikes, find a vet who sees poultry. Keep a record of your birds' ages, daily behaviour, egg production, feed, new arrivals, medicines and deaths. Those details help a vet assess whether one bird or the whole flock is affected. If you bring home new birds, ask the vet how to separate and observe them before mixing them with the flock.
Housing and daily welfare
Provide a dry, secure, well-ventilated house with perches and nesting space, plus room to explore, scratch and dust-bathe. The run needs protection from predators and should let birds avoid bullying. Keep bedding dry and remove wet or soiled material; clean feeders and drinkers regularly. Shade, shelter and water are especially important in hot weather. RSPCA guidance describes the different needs of a coop and outside run in more detail.
Chickens are social animals, but adding birds suddenly can cause fighting. Watch how the flock shares food and water, and provide more than one feeding point when needed. Check each bird at least daily: bright eyes, alert movement, normal breathing, appetite and droppings are useful baselines. A hunched bird hiding in a corner, limping, breathing noisily or producing fewer eggs needs closer attention and veterinary advice.
Feed safely
Use a complete commercial feed matched to the bird's age and purpose, such as a suitable layers feed for laying hens. Provide constant clean water. Insoluble grit helps birds grind food; laying hens may also need a suitable calcium source. Store feed dry and secure so that it does not spoil or attract rodents.
Do not feed household kitchen scraps or catering waste to poultry. This includes vegetable scraps from a household kitchen; the prohibition is intended to reduce disease risk. The older advice that scraps from the family kitchen are a harmless treat is misleading. Check the official feed rules before offering anything outside a balanced poultry diet.
Biosecurity and bird flu
Wild birds, their droppings, dirty footwear and shared equipment can spread infection. Reduce contact between wild birds and your flock, use dedicated footwear, clean equipment and control rodents. Check current bird-flu prevention guidance and any local disease-control rules; restrictions can change with outbreaks, so this guide does not claim that a particular housing order is in force.
Avian influenza can cause sudden deaths, a sharp drop in egg laying, swollen heads, breathing trouble or several birds becoming ill together. These signs are not a diagnosis, but suspected bird flu in captive birds is notifiable. Speak to your vet and report suspicion to APHA immediately. Do not move birds from the premises while seeking instructions.
When to call a poultry vet
Call promptly for a bird that stops eating, cannot stand, has a swollen or injured foot, strains to lay, has a prolapse, or shows laboured breathing. Multiple sick birds or unexplained deaths need urgent advice. Keep the affected bird protected and minimise handling until the vet advises; do not give medicines intended for people or other pets. For seasonal risks, see chicken heat stress and chicken winter care.
