I have 6 guineas that have been together for over 6 months. Today I noticed that one of them had blood under the wing. I got it in the chicken house to catch it and put some blue-kote on the wound. I then saw that there was quite a bit of blood on the ceiling above the roots in the chicken house. No animal could have gotten in to do this. 1. Do I remove the injured guinea? It seems to be fine and the wound has been treated. 2. What the heck is going on and how do I prevent it from happening again?
