My mother is selling me 22 Rir hens and 1 rooster for 50 bucks. I have 8 hens and a roo already. My birds are 8 months old. The new old birds are 3 years old and in my mothers opinion in poor shape. They are loosing their feathers and not laying consistently. I think I can bring them back to good health for many reasons. The main being I free range mine and she keeps them in a closed off retched coop and run (horse stall and 12 x 12 privacy fence). Any advice would be appreciated. I am to pick them up Friday evening.
