I set eggs under a broody a week and two days ago. I'm am absolutely positive the rooster is mating with the hens that laid the eggs. However, when I candled them at one week, not a single egg was developing. I feel bad for the broody and will probably just buy her a couple of chicks to raise if I still see no development by tomorrow. My question is this...how often is it that a rooster is infertile? I do know that sometimes he fumbles around a lot with the LF girls, but these were all bantam eggs. He is a silkie and is two years old.
