Gold laced Wyandotte sexing

[Blueroanpainted]

These guys are a few months old now, any ideas on what I have? Needing a few hens but I want to weed out any roos.
I marked them numbered 1-6 and as long as pics post in order. #1 has a white band. I've been trying to sex them myself but I am having a really hard time

How old is ' a few months' old? I do see several cockerels, but I think the age would be best to make certain.

Also, why do they all have white legs? Wyandottes have yellow legs.

At minimum 3 months but I don't know exact age. They could be mixes but I just need to know what is a rooster and what is not.

I want to say I got them the second week of March and they where around 10 days old then.
