I got 4 black sexlink babies in March. All were solid black with no white mark on their head.... so I assumed--and was told-- I got 4 hens. They are now about 7 months old. We are getting 3 eggs a day and one of our "hens" looks a lot like a rooster. We haven't heard any crowing or seen any mating, but this particular "hen" has a large cone/waddle, large yellow legs and pointed feathers around the neck. We just dont know for sure since the sexlinks are pretty much guaranteed to be a certain gender. I attached pictures. Thank you in advance for your help!!
