We put 2 young roos (4+ months) in with the hens thinking they were old enough to integrate them into the flock. The hens attacked them during the night or this morning and my favorite, Snoot, is hurt real bad. We have him in a cage inside, but he's having trouble breathing (like his nostrils are plugged, there was blood from them), they pecked his neck, head and face, and one eye is closed. Fidget is not hurt as bad and is still outside with the other chickens. When he was up, he did drink electrolite water (for 10 minutes straight he drank, a lot of it runs down his chest and just dribbles all over). He took a couple of pecks at some food but he is obviously extremely injured as he is unsteady on his feet, his eye is swollen shut (might be damaged, we can't tell) and mouth-breathing. It hurts him to touch him so I don't want to try to clean him off. We mixed antibiotics in with his mash, but he really isn't interested in eating. Any suggestions?
