During incubation, eggs must be turned several times a day to prevent the yolk from settling and help exercise the embryo, but turning the eggs by hand can be very time-consuming. The Hova-Bator Automatic Egg Turner saves you time and hassle by automatically rotating the eggs 6 times per day. This model holds a total of 6 egg racks that can accommodate eggs of many sizes. The turner can hold up to 41 chicken, duck, or turkey eggs.
