I have a male, 1 year, 2 months old. Has been completely healthy his entire life. He lives in a coop with 4 females. There are 4 other pens of birds, all inside of a locked barn. I picked him up today as I noticed a tiny bit of frostbite on the tips of his comb. I look at him very closely every day so this was odd to me, but it had been very cold (9* at night). As I picked him up, I noted pustules/nodules on his face and wattles. I immediately thought "Fowl Pox". Thing is, the flock is completely closed, no introduction of birds to the barn in at least 2 months. I noticed an injury of a hen in a different pen, but no other birds show any nodules, none are coughing, none are sneezing, wheezing...nothing. Is it possible it's a result of an allergic reaction to a different type of shavings? Could it be from rubbing his face against wire? From water splashing on his face and freezing? The nodules are on only one side of his face. He shows no other symptoms and is healthy, eating well and breeding everything in sight. Any ideas? He is in quarantine until I am comfortable with his condition being simply a slight injury.
