Nothing is worse than finding all your virgin queens dead due to an early hatching queen killing them. One of the best features of the Nicot system is that early hatching is unlikely because each egg starts off at nearly the same age. There are only 110 cells for the queen to lay in; therefore, she lays very quickly and all the eggs are within a few hours of being the same age. As soon as the queen cells are sealed a cell protector cage can be fitted over them so as to insure protection of the cell or containment of the newly hatched virgin. The cages can be further used for traveling and introduction. 10 count.
