One of my chicks hatched with a small amount of unabsorbed yolk. I don't see any bleeding and the chick seems energetic but the unabsorbed yolk is still attached to the shell and it's just walking around dragging the shell and tripping all over it's yolk sac. Not sure what to do here, I tried seeing if I could gently get the yolk to release but it's stuck good enough that I wouldn't be able to do so without tearing it. Do I just leave him alone in the incubator and see what happens or what?
