In my little flock of 16, I have about 4 that are over-preening. I watch closely and don't see them peck one another but these 4 have bald, red, but not bloody spots on their back (right above the tail). I have seen a couple actually peck that spot on their own backs. They eat 22% protein for egg production (I had read low protein could cause the pecking). I tried the purple no-peck stuff from the store but they turn right around and do it again... Also I have two feather footed girls that seem to open their mouths a lot. Almost as if panting, but it's not hot. Not sure why... Thanks for all the advice & tips!!
