Could they be coming out of molt, do you think? Better pics might help. Mine looked kind of rough after molt for a bit and weren't laying well. I put them on a higher protein feather fixer formula for a while. They got to looking just beautiful and egg production picked up as well. Do you guys think this might help?
Kind of late for molting but possible. Or just not kept in the greatest of conditions (if it's a feed store lot, my guess is all the available birds were just tossed in a pen together and some birds were probably beating up on others).
I don't do a protein boost for molting, but it probably wouldn't hurt here to try and improve their condition. Not entirely familiar with feather fixer but a grower feed could work too as it generally has higher protein. A small bag should do.
