We have a polish crested rooster who does his duties as rooster. We are on our second round of eggs in the incubator. The first dozen we put in the bator, there was no development. So after 6 days I pulled all the eggs out and started cracking. 7 out of the 12 were fertile, but it was nothing but yolk and white in the egg. So we tried again, we are now on day 4 of the new eggs in the bator and as of early this A.M. there is nothing going on inside the eggs. So is it something we are doing wrong that the fertile are not developing? We take them still warm from the nest box and put them in the bator. The bator is set at 99.5 on the dot and 45-50% humidity. Or, could this mean there is something wrong with our rooster? If the rooster is infertile, would the eggs still have the little spot on them that indicates they are fertile? Any help is appreciated!!
