I've done some searching but I can't figure this one out. Last night we were moving a flock of about 70 4 week old delaware chicks. One was moving erratically with it's head permanently in a position against it's chest Like it was completely obsessed with preening it's underside. We Isolated right away. This morning it is in the same condition. It is not listless. Poop is normal. Everyone else is normal. Any Ideas? Is this contagious? - Thanks
