I have a year-old barnyard cross rooster who didn't look well at all when I went to check on the chickens this morning. He was just standing in his pen and staring off into space and when he did move, he just kind of staggered around very stiffly. He didn't seem interested in his food, and I noticed that he seemed to have some yellowish discharge on one side of his beak. I checked his crop thinking that maybe he had an impacted crop, but his crop wasn't even full. He sounded very hoarse when he crowed, too. Also, he has been squinting one eye for over a week, but I'm not sure that's related. His eye does not look infected and has not changed in appearance at all, though, when I first noticed it, I did put some Neosporin on it in case it was an infection. I had also thought that maybe he had just gotten something in his eye that had scratched it and caused it to become irritated. I've never seen any of these symptoms before. The medicines I have readily available are Wazine, Sulmet, and VetRX (I know VetRX isn't actually a medicine). He is in a separate pen from the other birds, so I'm not too concerned about his passing anything to them. He was actually slated to be given to a friend of my dad's along with some young cockerels, but I'm definitely not giving him a sick bird. I added some Sulmet to his water before leaving for work just in case it was some kind of bacterial infection, but I really don't know what's wrong with him. Does anybody recognize these symptoms and know how to treat them, or if it's something I can even treat? Any insight would be greatly appreciated.
