I have been mixing layer and starter/grower feed together to give my chickens added protein. I have 1 girl that is quite bare and was hoping to help her get those feathers growing. I think they might be starting a molt now, they are just over a year. I am wondering how long I should keep them on this mixture. I also have free choice oyster shell for them and they get our kitchen scraps. Should I give them some cat food and some canned fish a couple times a week too? Thanks to all BYCer's.
