Hello! I have three hens that we hatched back in May. We had a rooster for about two months(August- first week in Oct) but had to get rid of it at the beginning of October. The rooster was also hatched with the hens so they were all the same age. A few days before the rooster left I noticed it mating with one of the hens.... Fast forward to today when we discovered eggs! The first eggs! So we cracked one open to cook it up and the yolk had the fertilized bullseye marking. I'm so flabbergasted by it, because it's been over two months since the rooster was here and there aren't any other roosters around. How is this possible?!
