My hen was fine last night and this morning she was hanging her head to the ground and it was angled to the right. I'm new to chickens and was searching for what it might be and it sounds like crooked neck, but I'm not sure. Is this what it looks like?
The crooked neck-thingy can be a sign of a vitamin deficiency or stress.
Watch her closely, and make sure she's eating and drinking.
You might try a vitamin supplement, especially if she's not eating.
If her neck gets much worse, you may have to feed her by hand.
If vomiting occurs, you may want to give her something with electrolytes.
We have a chicken who has a very crooked neck. It wasn't very severe at first, but it got worse.
