I know, how cheap am I? but here's the thing... I pulled out an old incubator that had set on a shelf since last july, and a mouse chewed a tunnel along the bottom with a hole leading into the inside. Tunnel is about eight inches, mouse sized. I can just put the plastic tray in the bottom and it will hold water okay... I could just set the bator on a folded towel and I'd guess it would hold temps okay... I got eggs coming from ebay and don't have time to order a bottom before the eggs will get here, probably Mon/Tuesday. As it is I am late getting this bator cleaned up and sterilized. It will probably still smell like faint bleach when the eggs get here. I wonder if home depot has any spray foam insulation goo stuff I could spray on the bottom and just set it on a piece of glass to set up if that would work. Has anyone here ever successfully fixed a damaged styrofoam incubator?
