There is an egg in my coop that is hatching! But I don't think it's coming out right. It has made a huge hole were it can get out but a membrane is holding it in. It has been over an hour since it started hatching. Is that normal? It broke a vein on the membrane and now it's covered in blood. What can I do to help it? It is balled up in a knot and I think that is why it hasn't come out.
