A friend got chicks two-three weeks ago, and one (a black Austrolorp, I think) sneezes and shakes its head frequently - like every few minutes. I believe it has been doing this since it arrived, or soon thereafter. It is a little smaller than the other chicks, but otherwise seems perky and healthy - eating, drinking, flying, normal poop. Any ideas for what could be wrong with it? Could it be something minor? It is separated from the others in an attempt to avoid infecting them right now. FYI,they are all on straw bedding in cardboard boxes inside the house.
