I have a week old Cochin chick I got from Meyers. She shakes her a lot, almost like an uncontrollable tick. She even does it while sleeping. Does anyone know what this might be? It can't be mites considering the fact the eggs are in the incubators and then hatch and head out for shipment. The chicks ever have a chance to e exposed to them. These are my starter folk, so there's no mites from here either. Any ideas?
