I new to this and bought a Little Giant as a 1st bator. I apparently didn't understand the "manaul" temp thing. I have battled with that thing like crazy. We have it bouncing between 99.5F & 100.7F. The rep. from the company said that was wonderful for that bator. Well, due to one being late coming in I was forced to buy another one of the same one. I now have a Genesis Havo-bator Electric on the way for my 3rd & last set for the year. I'm hoping that I'll have better luck with the temp thing.I have an old (borrowed) bator that I cannot seem to keep a stable temp in I was going to go get one but a good one is at least $300 I decided my next chicks could be under a hen
