I have one of t hose ones you put ice and pop in it. And it gets really warm inside and stays that way. do you think that I could use that to hatch eggs without having to add anything or at lest not to much to it. I want to hatch different eggs for selling at the local pawn shop and other places. I know that it will get at lest 90 in there maybe more depending on temp in the room it is at. What would I have to do to make that incubator. I also have small styerfom one with a lid. I need to make good one with the lest about of money going into it. So any help would be awesome. HELP me out the big incubators are way to much to pay for. So I need something else.
