I noticed one of our chcikens looks abit tatty earlier, kind of ruffled up a bit.
I watched her for a while and noticed she has a completly bald bum.
Theres patch of about 2x2 inches without a single feather.....I noticed the nesting box had lots of feathers in when I changed the bedding but thought it was just general moulting.
I#m not sure how another chicken could have done to beacuse they always sit with thier bums against the wall....anoher chicken woudn't be able to reach the feathers.
Shes prefectly happy, just has a cold arse.
any idea what it coudl be??
