I have a girl who lays no shelled eggs here and there. She has since she was young, but she also lays regular eggs (Fi my Golden Comet). Fi is also a feather picker. She was good all winter and started picking as soon as she started laying. not enough protein I guess? Which you would think is better now, they get meal worms, they find tons of earth worms, and i've been giving cat food soaked in water every couple of days. still picking, but maybe not as much. Constant struggle with the girlsBeen doing alot of work around the flocks lately and I know, but never paid attention, that I have a BO that lays a shell-less egg. I have found them in the nest box. I saw her do it just a while ago. I know I should look it up and probably will anyway but . . . . will she ever lay normal again. Additionally, I have a feather picker. This same BO has a feathless rump. I am sure it gets picked while they roost. Will that feather picker not pick feathers? What are your experiences chickeners?
If the picking get too bad, I will put pinless peepers on her. her and cluck-cluck have worn them before. We had such a good winter I thought we were done with that. Good luck!
