Hi, one of my buff silkie chicks about 12 days old now has started doing a weird yawn looking neck movement. She/he first opens beak then turns head to the side and looks like he's yawning kind of and dipping his head to the side. Something is wrong here,,,he's doing it about every 30 seconds right now. What could this be? Last week, this same chick had splayed legs. I used a brace and he's completely upright and looking great. NOW, this has turned up! What can I do??? What is this???? Julie
