We are the proud owners of a new bunch of week old Buff Orpington chicks. I noticed that one of the chicks seems to get its head stuck after it drinks. It only happens after it drinks and it gets its little neck stuck straight up like its looking at the sky and acts as if it can't get it out of that position. I can reach down, give it a little nudge and its fine and runs off. Any ideas as to what this could be?
