I had some eggs in the incubator that I thought were duds as everyone else hatched. I took them outside to open them to see what happened. The first one I *cracked* started peeping, so I ran in the house and put it back in the incubator. It hatched a short time later but it has a little red stump left on it's bum. So what is it. It looks very much like a baby's umbilical cord. I have the baby resting in the incubator still hoping that the stump will either dry up or be absorbed. Hopefully someone else has seen this and knows what it is and what should happen.
