1st time chick owner, sex n breed help

[Retrieverluvr]

All these Chicks are 3 weeks old

Here is my Mystery Guy from McMurray. I am figuring Rooster....but what breed?
Welsummer? Single Comb Brown Leg?






Blue Laced Red Wyandotte....Any roosters?





Silver Laced Cochin
I think the one on the left is a rooster..





Thanks for any help!!!! I am having so much fun with these guys!!!! I have a bunch of others too but they were sexed....so hopefully I wont have to worry about them being roosters!

the top looks like a rooster but cochins look like pullets but you should really wait until their fully feathered to try to sex them just by their looks

Hello, I would guess by that comb the first one is a boy. Not a wellsummer as I have wellies and they have pink feet. I think speckled Sussex and Easter eggers look similar to the wellies when they're younger so could be one of those. The other chicks I'm nit sure. The chick in the left in last pic could well be a little roo based on his stance!

Your BLRW standing up (with the darker red feathers) appears to be a cockerel.
