I'm new to chickens and have 5 one week old chicks. They have been sneezing a bit since I got them but two of them are sneezing more than the rest and scratching their faces. They are also breathing with their mouths open a bit when they are about to go to sleep. I noticed them doing this when I first got them but thought it was because the brooder was too hot (they stopped doing it when I moved the heat lamp back), but now I'm worried because of the scratching, sneezing, and heavy breathing. They are quite active and eating, drinking, and pooping normally and I can't see any discharge, but I can't help but be concerned they have a respiratory illness.
Thanks!!
Thanks!!
