I have 4 RIR hens that are all just about a year old now. When I first got them they all seemed to be laying. About 2 months ago the laying stopped completely. There were quite a few feathers in the coop and I just assumed they were molting. I never really noticed any bald spots on any of them except for 1. 2 of my hens are back to laying and only 1 of them still looks kinda rough. The rough looking one is missing feathers on her head and neck, but pin feathers are coming in in the bald spots. I noticed that the end of her wing feathers are all broken, is this a sign of bullying or just part of the molt. I have seen the other girls pick on her and she stays away from the rest of them most of the time as well. I wish I could figure this out, any ideas?
