I can't believe a good God fearing man can't buy a decent incubator. All they seem to sell is China junk plastic everything mine came pre- broken one of the trays the crank end was gone and it was also supposed to have a foam insulation outside lined NOT!!! It took me 2 hours to snap this garbage together . The perfect incubator in my opinion has a 12volt egg turner 12 volt heater 12volt fans and a battery that gets charged with the 12 power supply you plug in to your wall . If the power goes out it automatically switches over to battery power . It also needs to be well insulated to hold temperature . If I build myself I will have it my way, Any thoughts on this out there in the chicken world ?
