Today is day 20 on 7 eggs in the bator. The first 18 days the eggs were in a havobator with auto turner and fan and kept at a stead 99.5- 99.8. I have moved them to a hatcher which is a little giant, it has a fan but I turned it off for hatching. The temp is a steady 100 degree's and my question is should I leave fan on to keep the temp steady in the bator or should I leave it off. If off is 100 a good enough temp. I can only seem to get it to stay at either 100 or 102. I have both vent holes open and the eggs are in a plastic egg carton. Any advice would be helpful!
