I just bought 6 bantam chicks at the feed store. I have only had them a day and noticed one of them acting strange. One of the chicks will begin chirping very loudly and will start scratching like crazy at the side of its head. Usually one side then the other. But sometimes it will drop to the ground and scratch with both legs. Usually this only lasts 30 seconds or so. After I noticed it two or three times I separated the chick from the others. A few of the others are scratching a little but not any more than the normal. The chick acts fine at all other times and eats and drinks well. I tried to read up on it and thought it may be mites but wasn't sure. Does the sound like mites? And if so what is the best treatment?
