Also, the incubation temperatures and humidity were set at 89F and 99% respectivelyh. There was a period early in the incubation that the internal tub temperatures had fallen to 85F by temp gun as I had found out days later. We know how the early environmental conditions are so important for the eggs and development. That , more than likely caused the delay in pipping. I did wind up cutting all the eggs realizing none had pipped. Never dealt with something like this in my breeding career. These guys actually remained in the eggs until July 10 before emerging.
