A have a chick with the yoke on the outside. It looks like it is, I don't know how to explain it but. When you open an egg to eat it how the yoke has a skin on it. Well it looks like the skin is still there and only a little yoke. It seems the hole is closing but the chick is shaking and will not get off its back. Should I cull it or wait. I don't want it to suffer. Thanks for your help.
