I have had about 4 successful hatches in my newly acquired humidaire. This last hatch, I started with about 30 eggs and 17 made it to lockdown (they were mostly shipped eggs). Come hatching day, nothing happened. Nothing ever did. I opened one up and the chick was developed but had died. It did seem that the air sacs were unusually large and I was having trouble keeping the humidity up, which had never happened before. Meanwhile, I have a very high end thermometer in there and the temp was stable. Any ideas as to what might have gone wrong?
