I have a young pullet that limped up top me today with blood all over her head. I put some neosporin on the open wounds but I have no idea what happened or how to keep it from happening! I have two young roos right now, too (one has a new home lined up as soon as he's big enough to go), and one of them has shown some aggression towards the pulleys but not THAT much!! I let them wander in the afternoons, but I regularly walk the yard to check for hazards so i can't think what happened! I'm posting some pictures if the wounds and a quick video of her limp. Any suggestions?? I've raised chickens since I was in elementary school and I've never seen this before!
