i have done the day differences in little giant strafoam bators, one day i dont worry about turning, if two days difference then i still turn,keeping cover only open high enough for hand to slip in,or by poppin open a window, and be fast about it....maybe you posted it & i havent had a chance to read about your homemade bator....what did you use for holding containor ? i have years worth others information waiting for that day. i wanted to go BIG ...old refrig...but realisrically figured i best stay with med size cabniet. so my summer project is to build my own bator. everything ready for project.. my biggest hurdle is what to use for a turner. ......
