at that photo, you cannot tell if it has issues, at that age, he would have a time getting up. Only after they have poofed can you really tell what the issues are. I have an Ameraucana, Frieda, that has curled toes and when I finally found this out, they were a week old. As long as she can keep up with the other girls, she sleeps on top of the nest box (I allow her to) and put shavings up there. Of course if you cull now, you will not get attached. You have the choice, I'd wait a day and perhaps nature will take its course.
