I have been hatching chicks for at least a week now, through scattered hatch dates. Today I had three chicks hatch fine and 2 more are pipped. But when I looked closely at the third I noticed it has a little bit of a blood bulge around the area where the umbilical cord disconnected. I think I have had this happen with a chick before, but I don't remember what happened or if that chick survived. The blood is dried but I worry about the others pecking at it and pulling out internals or injuring the chick in some way. I have not taken it out of the incubator yet. Will the bulge absorb back into the chick, or is this something I should be worried about? I can't post a picture of it because I don't have a device right now capable of taking the shot. For reference, the buldge is about the size of a small pea,
