We adopted 3 chickens earlier about six months ago from a friend.Our Buff keeps having these reoccurring open wounds on her feet/ankles. If you look at the pictures, you will see a wound on the foot on the right. The wounds usually happen on both feet in nearly the same spot at the same time. This is the first time it's only on one foot. At first, we thought she was getting caught on the chicken wire, but we built them an enclosed run. It happened one other time, and again today. We put Blue Kote on, and they scabbed up and healed. I'm not sure what this is or why it keeps coming back. This time, it looks more painful - she limps and does not want to put pressure on the foot. Any advice on identification and treatment would be great. Also, should we separate and confine her to a smaller space that does not allow lots of movement?
