Feather Moulting

About Feather Moulting

Moulting is the replacement of old feathers with new growth. Egg production often falls during this period. In Australia it commonly occurs around autumn, although age, individual birds and conditions affect timing.

What can cause it?

Normal feather replacement is part of a bird’s cycle. Feather loss can also result from parasites, pecking, injury or nutritional problems, so do not assume every bare patch is a moult.

First steps and veterinary care

Continue an appropriate complete ration and fresh water. Provide shelter and gentle handling because growing feathers can be sensitive. Watch that quieter birds can reach food and are not being pecked. Never withhold food or water to induce a moult.

Prevention and everyday support

Keep the flock well nourished, housing clean and behaviour under observation. Check for skin damage and parasites rather than treating feather loss on appearance alone.

When to seek help

Seek advice for bleeding, inflamed skin, persistent bald areas, weight loss, reduced appetite or a bird that seems unwell.

Support for your flock

If your chicken is unwell, contact a poultry-experienced veterinarian. Take notes on signs, when they started and how many birds are affected. Photos or a short video may help your vet.
