Newly arrived SLW she is twisting her neck at this weird angle and twitching randomly. Drinking seems to trigger it sometimes but it can come on randomly. Looks like her head is on backwards and she chirps loudly while it's happening. No other abnormalities that I can see. When not twisted she moves fine and is active. When twisted she falls easily if bumped or if she tries to move. She is drinking but I haven't witnessed her eating yet but I could have easily missed it. None of the other chicks or ducks that arrived with her show any symptoms. Oh and despite looking tiny in the picture she is normal sized just being housed with older chicks. Any ideas on cause or treatment? I know I need to confirm that she is eating but I'm not sure what else to do for her.
