I put 21 eggs into my homemade forced-air 'bator 7 hours ago. Since then, though the air temp in the bator has come up to 101, the temp inside the wiggler (measured with 2 different digital probe thermometers in the same wiggler) has not come up above 96F. Can anybody explain this? I know I can't count the first day of incubation as part of the 21 days.
