you should just let the lil guy be and how he grows, the kink may or not cause any problems. i still think it had sometihng to do with the incubation. and as Gale said above you prolly shouldnt try breeding him.
in the pics the sire looks like a typical pastel and the dam looks like a normal, he should pair them up again and see if something like this guys pops out again. but make sure his incubation is spot on to prevent something like this. if a healthy oddball pops out again then hopefully its male and you can breed it back to mom and see what happens.
