DH and I put our 8 RIR eggs in for hatching on the 10th of April, and they should have hatched out on Thursday. We did not have a hygrometer and since it was our first hatch, we waited a couple extra days before calling it quits. I wanted to open the eggs to see how "far along" they were and found most were not fertile or just didn't develop, one died about 5 days before hatching, and the last 2 are back in the 'bator. I cracked open the aircell and they were moving well and one was even peeping. One tried to pip earlier today on the side of the egg, not near the air cell and is loudly peeping and moving well. The opther is not peeping, but is still moving. When do I say enough is enough? Will they make it?
