I think hens. whatever they are, if they were different you would without a doubt know which were which. I had two and by five weeks I could compare the two and tell the cockrel from the hen. However they are quite red, so maybe cockrels??
They both have such red combs. I am thinking the second one must be a roo. The first, it has a red face, way to red to be a 15 week old pullet. Probably a roo too.
With EE's, there are other ways to identify their gender. Color is a huge indicator. Could you post some pictures of them showing their bodies?
