One of my Barred rocks is kinda moping around. She has lost color in her comb but her waddles is still real red. 3days ago another chicken was pecked down to the skull in the back of the head. Is it possible the barred rock was the culprit? Is she getting sick because she ate the feathers, skin, fatty part, and blood? Or is it that she is getting "broody'? She is also losing some feathers. At least they are all over the run, but she still looks fully feathers...could she be molting?
