I'm a brand new poster to the forum (have been reading for months), and have had chickens for one year. One of our girls has been losing feathers around her preening gland; a couple even look broken. Any ideas?
FYI we have 3 Plymouth Rocks all one year old and one 5 year old Australorp or Jersey Giant that we inherited. Not for nothing, but we're also pretty sure that the old lady is eating eggs. She doesn't lay anymore.
Thanks for your help!
