I'm concerned about my 11 month old rooster. He's eating, drinking, and makin' sweet love to the hens, but his feathers are not looking so hot and this morning after drinking water, I observed him have a thick, foamy spit come out of his mouth. I observed the whole flock for a good 20 minutes after that and none of the hens seem to have any problems. The rooster did make one noise that seemed a bit wheezy, but other than that he seemed alright. The girls are kind of tough on him, and I have lately observed him fighting with one of the hens. And I mean like chest bumping, wing flapping, brawls. He wears a No Crow collar which I think may be causing some damage to his hackle feathers. Also, the girls have plucked out his tail. Things are rough for the poor guy lately! Main concern is the spit. Is it likely a respiratory infection? How do I go about treating that? I'm including pics I took of him this morning that show his feather damage, just in case it's relevant. He's an FBCM, and as you can see, his copper hackle feathers are not looking so hot. Thanks for any input!
