I have one an if you check my posts you will see I don't like it very much! I thought when they started to hatch my worries were over Ha HA Wait till you have a few chicks in it talk about temp. movement goes through the roof. It went as high as 104 down to 97 If I had read this form before I bought it I would have bought a Hovabator Genisis. They seem to stay more stable. I put 16 eggs in 21 days ago an I feel lucky that I have 9 hatch an a few more on the way. The one thing to remember is keep it in a room that dose not have a temp. swing. no drafts. In WV this time of year it is really hard to do that. Good luck (I know you will enjoy the chicks)
