I acquired two chickens in June that were being bullied at their previous home. One of the two was in a real state with a number of feathers missing. The feathers have still not started to grow back and she has gone broody and some more of her feathers appear damaged possibly from sitting in the nesting box so much. I know they can get lice but have not seen any signs of them and the other chicken looks healthy. Would her feathers not grow back until she moults & should I worry about the damaged tail feathers? :unsure:
