It's day 20 of incubation and one of my chicks has already hatched. She started with some yolk sac showing (maybe the size of an m&m) but as she's been moving around more is appearing. We're talking larger than a quarter size. She was acting pretty much like I'm used to seeing a new chick act, but the amount is a definite concern and she seems to be weakening. Is there anything I can do to help her or am I probably going to lose her?
