I have a RIR/Leghorn cross who went through a molt early spring. She is just getting her blood feathers on her neck but her breast and butt are basically bare. The other girls are REALLY picking on her and she is stressed and has lost weight. Her breast bone has a scab where she roosts due to bareness from feather loss. She is not laying (not a problem for me). I have decided to separate her in a cage next to the coop where they can still all see each other, but they can not attack her. She is eating and drinking well. She free ranges with my supervision for her protection. My question: What can I feed her to increase weight but maintain health? Any suggestions??? She presently on layer feed and some fruit treats.
