I had 4 jersey giant eggs incubating. I'm on day 23 today. Last night, day 22, one chick hatched. 2 more hatched today. There's still one left. I took it out thinking it was dead. Candled and it's still alive. I'm almost through day 23!! Why hasn't it hatched yet? The temp is a stable 99-99.5. Humidity is fine too. Is it hopeless for this little guy? Or do jersey giants take a little longer to incubate?
