Health & Disease

Guides to common chicken illnesses, parasites, injuries and poisonings: what the signs look like, what causes them and when to call a vet. Every article in this section has been checked against veterinary and university extension sources, which are listed at the end of each article. Our writers are not veterinarians, so use these guides alongside advice from a poultry vet. If birds die suddenly or show swelling, purple discoloration, gasping or twisted necks, contact your state veterinarian or USDA (1-866-536-7593) right away.
