This one I think is definitely a cockerel. Any thoughts?

I’ll post the others I’m unsure of in another thread.

8 of them look very similar, except the hens (I think they’re hens due to small comb)

All of those are cockerels. Most are production blues (also known as Rhode Island blues) except for the amberlink. They’re a hatchery-made hybrid.

What about these 2? These are Americauna, I believe.
