Ive recently hatched two silkie chicks out of 10 eggs. One of them really loves pecking the other one on the head, it had been happening since they first hatched, 4 days ago i noticed the one getting pecked acts really weird. He often tilts his head side by side weirdly like it was heavy or something. It usually happens when he is pecking at something like food or when he drinks. He also holds up his head weirdly at times. Anyone know whats wrong and what to do?
