The other day I noticed my chicken, Sammy, was missing some feathers on his chest and back. I only have two chickens, and the other one is lower on the pecking order or so I thought They both grew up together since chicks and they never had any problems until now. Here are a couple pics of Sammys chest: Here are a few pics of his back: Here is a pic of them together: Anyway, I dont know why this started. Any thoughts? And does anyone know something I can feed him to better help his feather growth? Should I separate them? I didnt want them to be lonely, but if its for the best... Also does anyone know the gender of them? I know the silver chicken is not a close pick (Ill try to get a pic tomorrow), but I am almost sure Sammy is boy. So, any advice? Thanks in advance!
