Originally thought the chickens were molting. They are one and a half years old. Unfortunately the neck feathers have never come back again, very minimal feather loss anywhere else. No mites that we can see. No rooster. They are still laying normally.
This is "Sookie" , supposed to be a pullet Easter egger. About 5-6 weeks old. Has the reddest comb in the group (it is brighter in person) and does some chest bumping frequently. Any thoughts from the experts?? We are newbies! We wanted to avoid roosters... Thanks for the input.
