Tomorrow morning I'm picking up my new to me bator. I've been told it's a Hova Bator but the kid who has it doesn't have the manual anymore and cannot remember what model it is. He had a bunch of bators that he used to use for reptile eggs and was unloading them cheap since he doesn't use them anymore. Apparently it's really clean and works fine. I have never used a incubator before, how do I use it? He mentioned that I would need to get a digital thermometer that does temp and humidity and that you control the humidity by pouring water in the bottom? Even if it's immacuately clean, should I clean it prior to use? If so, how? Is there anything special I should know about where in the bator to put the thermometer? Thanks guys!
