Recently my chicken was losing feathers on her back near her tail. My husband thought it was molting but the bald area is getting bigger. She has some feathers that seem to be broken in that area too that won't heal and recently started bleeding. I'm bringing her to the vet soon, already have the appointment. Last time this happened I needed to keep the chickens separated until the injury was healed and was put on antibiotics. It is cold now, about 30 degrees on average. So I can't leave her alone in a sick area coop. Knowing I need to keep her separate until she is healed, what is the best way to reintroduce the chickens when she is healed? And does anyone have any recommendations for knowing which eggs are hers to avoid eating them after reintroducing them?
