If you search the forums there are posts on giving them additional vitamins that may help straighten it. It's a problem it the skull itself. i have one that is about 5 months old, she is a bit smaller then the other but she is doing ok. Her's is as bad as it can get, her bottom jaw is totally out to the side. I have trimmed it back and the top one a bit too so she can eat, she can only eat out of the trough where the food it deep. She uses her tougue to pull the food in. She is the toughest chicken I have too, she will chase all the others away from her "food dish".
