Help! I noticed today that my favorite hen, a red sex link, has a large bald patch on her stomach. I didn't see any lacerations (although the skin is pink/reddish) and she's not being picked on by the three other hens. But a few weeks ago, a stray husky got into the coop (kids left the door open... ugh) and got a hold of her. I managed to shoo it off before it killed her (it ended up killing one of the other hens). Any ideas what might be going on? Or how to treat her? Thanks for any advice. I feel terrible for her. I've never seen a bald patch on any of my hens before.
