I just cleaned the coop Sunday and saw no signs of any issues with the coop, run or birds. Today when I let them out I found my Buff, three Rhode Island Reds and an Easter Egger with bare...ummm....underbutts? I know we have a pecker in the flock because two of my EE's have bare backs but they've never pecked any of the others. Is this possibly a parasite, pecking or what? Sorry for all of the chicken tooshies.
