Why is my Brower Top Hatch incubator impossible to set? I cleaned it well before I stored it, set it up 3 days before I put the eggs in, and fiddled with the temp until it was right. I put the eggs(10) in last Saturday, and it's not held since. Temps from 87-102! Right now it's under a towel to keep the temp up. Can the thermostat be shot? It's only a year old. The turner is fine and it's holding humidity. We do keep the house cool, but it's in a draft free bathroom. Any ideas???????????
