Last year we had a double het clutch of albino to pied, 4 eggs. Incubation was fine. We never noticed a temp spike or power outage. Eggs pipped on their own at day 57. Three hatchlings crawled out and were perfect and the last baby never came out. As for as I could tell he pipped his egg and just died. He (I never sexed him) had a very small lower jaw and his neck never separated from his belly (I hope that makes sense). We have been breeding a while now and that was our first defect....
