From looking at the comb size in the first pic, I was thinking roo for sure, but then I saw that it had the color of a red sexlink hen. Now I have had a roo before that was the same color as a red sexlink hen, though they weren't sexlinks them selves and they didn't produce sexlinks. So do you know what breed it is supposed to be and where did you get it from?
I'd say male. This color patern is the color of the male offspring of some red or gold sex links but not all some are mstly white. Look at Ambers on feathersite. page.
