Correct me if i'm wrong but how long have your eggs been in the incubator like 5 days. If so you need to wait til about 10 and recandle them to make sure you have more than 5 fertile. Also the hatcher is made to raise the humidity if you have staggered hatchs. In other words don't try to add eggs a week or two later and then raise the humidity for the first batch. The first batch would go in a hatcher with the humidity already raised.
