I just picked up 2 chicks from a feed store yesterday. They are acting completely normal exept some sneezing. Neither of them were doing in on the ride home, me and my sister were holding them. I wrapped them in a blanket that had a stronger smell from being stored, so am thinking that may have been it. But wanted to see if there are any other things that could cause such things. I want to get rid of this, as want to see about getting a few more chicks later this week.
