I just got a new incubator, a friend used it once and said it worked fine. HHD 48 incubator. Cheap quality but it ran at digital reads 38C and 50 humidity just fine. I read someone say put in your own thermometer, I put in a cheap $4 blub type which has been used alot and is older. it was reading 110f. on top of the eggs. Sigh. I am hoping the 110f was a mistake.... or, I have no other thermometers to compare with. I can get more eggs...
