Hello fellow chicken lovers... I would love some advice / assurance if anyone can give it. I have three hens obtained from poultry auction 7 months ago. One of the hens had no feathers on her bottom. I assumed she was bring picked on by her previous flock and that's why she ended up in the auction... I did lots of research and have done all I can to help feather regrowth, extra protein, Avia Charge, mite treatment, worm treatment etc. But nothing has helped. She is otherwise healthy, lots of feathers on the rest of her body but no egg laying either... I bought myself a free-loader . The skin on her bottom is exposed all the time and I feel sorry for her in the cold. They are in a slightly warmed shed for winter due to icy Manitoba winter. Any advice would be hugely appreciated!
