We have hatching eggs on the way and I am going to be putting as many as possible under our broody... but there is no way I want to waste eggs that don't fit under her. My problem is we are in a rental now and can't afford to be keeping the whole house heated to keep the incubator temps more stable. We are headed into fall and the temps in the house get into the 50's. We have a hovabator and I was wondering if it would help to put it into a large cardboard box and cover it lightly with a piece of sheet so can still 'breathe' ? What I have done in the past was keep a 'spare' bathroom warm with a space heater in it and that worked well, just wondering if I can do something like this just on a smaller scale. Has anyone else done something like this?
