Yes some times chicks hatch from the wrong side of the egg.This one was the last to hatch and has a bit of a curled foot so it’s not wanting to stand a lot. It can stand and does walk but I think it was in the shell to long or maybe malpositioned. All of the Marans pipped on the wrong end of the egg.
As long as they hatch I don t see the problem .
