These 2 are about 18 weeks old. I am new to this breed so not sure how to tell if they are a roo or hen. One has darker feathers on the comb than the other. Roo or Hen? The other white one in the pictures is a white rock.
looks like 1 hen and 1 roo. I think one is a roo by the slight downward curvature of the tail. Its hard to tell because they are feeding in these pictures. However they could bothe be pullets. Could I have a picture of them stood up straight side by side. I can tell you exactly what they are if so.
Looks like a hen getting ready to mature with the hot pinkish face. The legs of a boy would be thick, your chicken's legs are the same thickness as the white rock hen, which, in turn, means female. It looks like the neck and base tail feathers are all rounded, roosters have long pointy feathers.
