Ok so i bought a hovabator that had only been used once. I attempted to hatch duck eggs but had a hell of a time keeping the temp at the appropriate level ->only one egg hatched. I had to put the bator in a closet with a heat lamp over it just to keep the temp steady. Any ideas why the bator wont keep the high temp on it's own?? I want to get some turkey eggs to hatch, but now until i have this sucker figured out. Thanks!!
