When I ordered my dark egg layers I had ordered a banevelder rooster a welsummer rooster and a maran rooster with their matching hens. After some unexpected mortalities I still have the cuckoo maran hens the welsummer hens barnevelder hens but just a welsummer rooster. So my question is if I hatch out the chicks will the welsummer maran crosses be sex link? And will the chicks from these breed mixes still lay dark eggs? Pics of these crosses would be appreciated if anybody else has hatched any like this.
