Hello everyone. I'm new at chickens but have been around exotic birds all my life (46 years). Here's my problem. I've had 2 groups of eggs not hatch. First group only 1 chick lived 4 days. I live in Colorado at 6400 Ft with only 10% humidity and tried to hatch in October and November. What I have is a sterilized Hova-bator model 1602N with automatic egg turner( borrowed and sterilized with bleach, hot water and 3 days sunshine to air out any residual), and a electronic probe thermostat with humidity readout. I've kept the internal probed on top center of eggs with a temp of 101F and a constant 60% humidity. The temperature never exceeded 102F nor dropped below 99F and humidity stayed constant. Tried 2 batches of eggs of different breeds of chickens, one from my chickens and one from a friend 8 miles away with 50 years experience with chickens who has never had this situation happen (his incubator that was using to hatch quail). The eggs reach approximately 14 days and die. Anyone have any idea what is occurring?
