I have 6 poults, about 10 weeks old, and one of them seems a little weak and has a ragged tail. I came home a couple of days ago and there was a hole in the cover of the pen, about a foot wide, and everyone was huddled in a corner, with this one under the tom. The tom seemed to be protecting him and the others, while the hen was on watch. The "injured one" doesnt have any visible injuries, and is eating and walking around, but occasionally will sit still and close it's eyes. Do I have to worry about infection? I just don't know what to do!
