We started eggs in our Hovebator 2362n . We ordered new one since we are doing a staggard hatch of duck and chicken eggs. It has not come and the only thing locally I can get is the Hovabator with no fan. Our first set needs to be out of the turner Thu 2/25/10 . For the hatching/peeping duration can we use a fanless incubator. Will the humidity stay stable? Please any info.......
