What about the huge frame and thick legs?
Their breed makeup is unknown, so it is possible that their coloration doesn't present with typical male coloring.
Alright, I've zoomed in on the hackles of both birds. They are obviously pointed.
I've gone through enough cockerels at this point, EE included, and know them when I see them.
I've even been correct from as early as 1 day (not sex linked). For 3 years, I've gotten 95% correct. That's better...
