Is sneezing always a respiratory issue? I have a sneezing 9/10 week old roo. It looks like he has a bit of mucus on one nostril, but he is still running around like the crazy roo he is, and eating and drinking. Eyes are clear, and no other symptoms. These are the guys that went out to the coop Sunday night. Has been warm...until last night, dropped to the low 70's during the day, and I forgot to check the temp this morning.
