I have a campine rooster almost 2 years old that has been wobbling about, acting lethargic, and has a bad case of lice. I've been treating with Sevin Dust, but the wobbling and lethargy started before that (a few weeks back). I found him outside of his normal run today, panting heavily and laying down with blood on him, probably from the other rooster. I brought him inside to cool down since it's 90+ here in Texas, and he's steadily improving. His comb over the past weeks has been drooping, none of the other chickens in his pen have this issue. Is this from the lice or over heating or what? I've heard some people say do a fecal and other people suggest it's just the heat, but I'm not sure. Any ideas what may be causing this?
