I would say none are definite, given the variety of opinions already postedAre any of these guy’s definite roosters
Personally, I think you might have several males: #1, 3, 4, 5, 11, and maybe #2
#8 looks female to me. I am pretty sure the front photo-bomber in that image is a male (is it #3 wanting an extra view?)
I'm not sure about #6 and #9.
I do not see any numbered 7 or 10. (That could mean you did not post them, or that my computer missed loading a few image.)
I like the way you circled the birds and put numbers. It makes it very easy to talk about each bird without confusion
