If he's eating fine, then it's not a problem right now.Possibly, but I think his whole beak is crooked as opposed to crossed. I’ll have to look closely tomorrow, but I definitely see him eat food, grass and treats all day long. Is there a serious issue I need to look out for?
Given his current age, I think there's a good chance he will continue to be fine.
Just look on occasion, to make sure he's still able to eat, and that the beak is not getting too long. If it does start getting too long, the tip can be trimmed just like toenails can be trimmed.
Severe crossbeak can make a chicken unable to eat, and then the chicken doesn't grow right and isn't healthy. Also the beak doesn't wear down right, so it gets too long, and that makes the problem worse. Eventually, either the chicken starves to death, or the owner helps by providing special meals. But as long as your bird is eating fine, this does not apply to him.
