So this is a new problem I haven't encountered before, can anyone advise? We are mid-hatch of a batch of 34 eggs. One chick hatched this morning with what looks like a bloody mass (intestines? unabsorbed yolk?) hanging from its navel, and the navel isn't closed. It bled for awhile after hatching, but now the bleeding has stopped. It still has a jelly-like mass at the navel area that's bloody looking. I'm keeping this chick in the incubator with the other eggs that haven't hatched yet, as I definitely don't want it exposed to the other chicks hatched yesterday! What IS this? What are the chances it will resolve in a few hours? Should I just cull the chick?
