Backyard Hen Welfare: Common Health Problems

Backyard hens face a range of common health problems that owners often lack the knowledge to recognise and treat, requiring education and access to avian veterinary care.

Key Facts

Red mite (Dermanyssus gallinae) is the most common welfare problem in backyard hens, causing anaemia.
Respiratory infections, sour crop, and egg peritonitis are frequently fatal without veterinary attention.
Hens hide illness until severely compromised — daily observation is essential for early detection.
Ex-commercial hens often arrive with pre-existing conditions including feather loss and reproductive disorders.
Access to avian-specialist veterinary care is limited in many areas, creating welfare gaps.

Welfare Considerations

Backyard hen welfare depends critically on owner knowledge. Many owners who keep hens as pets rather than livestock are unaware of common diseases, parasite infestations, and the importance of daily health observation. Red mite infestations cause severe anaemia and overnight distress; treatment requires systematic application to both birds and housing. Many serious conditions are treatable if identified early. Accessing avian-specialist veterinary care is an important responsibility that prospective hen keepers should research before acquiring birds.

What You Can Do

Inspect your hens daily for signs of illness, injury, or parasite infestation.
Check for red mite weekly in warm weather by placing white paper under the roosting bar overnight.
Identify your nearest avian-specialist vet before acquiring hens rather than after a crisis.
Treat for red mite preventively in summer using approved products in both housing and on birds.
Join a backyard poultry community for ongoing education and peer support for hen health management.
