    I have a Swedish Flower Hen that I think has turned into a Roo. I have 4 chickens. No males. All 4 chickens have laid eggs. I am only getting about 1 egg every other day and they are fertilized. They have the little bullseye on the yolks. Any thoughts? Has anyone else had this happen?

    I have seen threads on this before but I feel sure hens that take on the role and features of a rooster are infertile, I may not be right however. Are you sure she isn’t just a slow developing cockerel? Do you have any pictures of the chicken in question?

    They can't completely change sex, with functioning gonads and reproductive capability and all, but they can have basically a hormonal imbalance that causes them to take on masculine traits like a rooster in appearance and behaviour. Either you have a sneaky slow developing roo masquerading as a hen, or the bullseye isn't due to the eggs being fertilized but something else. ... Or maybe there's a cheeky neighborhood roo doing a bit of fence hopping for some fun while you're not looking, haha. Do you have some clear pics of the eggs or chicken in question?
