Hi one of our comets has had a bare patch for going on 5 months. It looked like a dime sized wound at first but then got progressively worse. I sprayed blue kote on it occasionally but that just seems to irritate the poop outta her and everyone else. Not sure it's even needed. Does anyone have any ideas? Are picking at her? We recently started letting them all free range as it seems some of my girls were losing feathers to which I attested to maybe some picking in the run. It's a very big run but I think it just didnt provide enough entertainment for them. I fenced in the entire property (3 acres) with a 5 and 6 foot wire fence, and they now have about half of that to range. Here's a pic of our hen. Zoom in on the wing. She wouldn't let me catch her so had to get from a distance. Oddly she's the only one that runs from me.
