Here are 2 cochins that are most likely males and are feathering slower than the other cochins. The buff ones I got from TSC so I don't know what they are. My hen gladly accepted them with her cochins.
It has been in my experience that male cochins feather slower than female ones. I know some people will disagree but it's been 100% correct with all my male cochins. So your frizzle will most likely be a male.
