I am new at incubating eggs. I recently bought a Hovabator 160N Incubator. I am aware that humidity should be kept between 40 to 50% up until the eggs are 3 days out of hatching then the humidity needs to be raised a lot higher. My question is what about the people who, like my self, add eggs every few days after they are laid by the hens. I will have eggs that are close to be hatched at the same time as eggs that are only half way or a few days into the incubation process. How does one handle the humidity then? Thanks in advance for all of your help.
