I found one of my roos with a partial scalp this morning. He does share a cage with another roo, but has done so since they hatched 3.5 months ago. The injured roo is the "dominant" one, although neither have ever fought with one another that I've seen (and we watch them all the time because they're on our porch). I'm not sure what happened. I did add wire to the outside of their cages to raccoon proof it, so I suppose he could have scraped his head somewhere? I can't find any blood on wire, though. I put antibiotic ointment on his head. I'm not sure what else to do. He really needs it stitched. I'm considering superglue. Thoughts?
