Okay so this one hatched later with green goo in the egg and what I believe to be the yolk sac still hanging out. No blood and the others had be removed. So I left it in there. The yellow is gone and the sac looks empty and sticky looks like it was bleeding overnight there's a lot of dried blood in there but I don't see any fresh blood. Can I tie the sack off or is they're a way to remove it? It seems to be a little more tired than the rest but other than that acting normal. It feels like maybe the white or yolk dries all over it.
