I am starting to think my rooster is racist!! I have 2 brown egg layers and three white. No white eggs have been fertile up to now (I have incubated 30 - in two different tries a few weeks appart - after I posted some pics and we thought they were fertile, but after cracking them open after 19 days I see just a yolk). But, I have incubated about 22 brown eggs that were fertile. What's that about?! I didn't even think it was possible that a rooster be selective. The hens all have the same age, arrived at the same time in the coop (many months before the rooster) and lay regularly. They are always all together - the browns one don't have any special time with Mr Roo. One of the brown layer is slightly larger, but the smallest one is the same size as the white layers. I would find it strange that all 3 white hens would refuse the rooster's advances.. I know the rooster is young - he is 5-6 months old, but since he can fertilize successfully the brown layers, I don't see why he wouldn't go with the white ones. Anyone have any idea what could be the reason?
