7 week old Wyandottes - did I sex them correctly?

I don't think this video uploaded with sound. I think I figured out my Wyandottes genders. The first one I point to is a boy, then girl, girl, boy. Does this look correct? 2 of them are crowing. The one at the end I know for sure one was him. He has a bump on his comb so he's easy to spot.

Looks like you may have 1 female in the group the rest are boys.

Is it the single comb female? I have been suspecting she's a female for awhile. The other one I thought maybe is a girl because she doesn't have black around the neck. Unless I just haven't seen it well.

Yes, you're correct on genders.

It's the one with the rosecomb with dull brown lacing. Your birds with vibrant reddish brown lacing are males.

Don't be fooled if you only hear 2 crowing, with that many cockerels there's always the leader that crows and last one stays mute.
