hey yall, I was cleaning out my brooder and as I was putting the chicks back I noticed my Delaware would occasionally sort of jerk her head to the side of towards her body? it only lasts a few seconds and there's no other symptoms, she's responsive and eats and drinks fine. no other chicks seem to have this problem either. beforehand I fed them moistened feed if that helps. I currently have her separated, is there any way to treat her?
