I agree with previous poster, Silver Laced Wyandotte. As long as they're SLW, they're both [in my opinion looking to be] pullets. Cockerels have much more white. Beautiful birds!
I also have two SLW's. When I was concerned about one of them being a cockerel, I posted here and was told about the cockerels having so much more white. After rethinking my reply, I should have said that in my opinion, they're looking to be pullets, but my thoughts come from the two I have and that isn't much, compared to so many here.
