Partridge Cochin hen or roo?

[learningboutchickens]

Hi all, my family and I new to backyard chickens this year and have a few that we are trying to ID as hens or roos. Rather than continue down the Google search rabbit hole that I find myself in daily, I figured I would see what the thoughts are here. I will start with our 12-week-old Partridge Cochin. Thanks!

Cockerel, he has the male feather pattern and big comb.
