OK its been a bit since I had older chickens, just got restarted this spring. I just adopted two under weight 3 year olds. They came froma situation where the lady was overwhelmed and she was feeding bread and peas. Any way their feathers are all broke. Is it maybe a molting thing or is it possible to get their feathers healthy with time. I added a pick of a few from the Sussex. They both seem dull and rough. But otherwise pretty healthy.
