Pullets or cockerels

[myelli]

We’re new to chickens. We have 9 week old baby chicks and I think the hatchery sent us some males even though we only ordered females. We had 16 and now we have 14, since we lost 2 due to failure to thrive/runt. We ordered Ameracaunas, buff Orpingtons, silver laces Wyandottes, Rhode Island Reds and Barred Rock. We did get one that we believe is a Cochin Bantam and possibly a roo.
Can you help me confirm who are pulleys and cockerels? I believe one of our Ameracaunas are, but I’m hoping that is all. Hopefully no more than the 2 we think.

I think you are right. Your cockerel is the EE in the fourth photo. The black cochin might be a cockerel, but it is definitely not certain as of now. It should be much clearer in 3 weeks

Agree

At least to me, they all look like pullets other than the one in the 4rd picture.

All currently look like pullets besides your 4th photo EE. The Cochin I think is a pullet. My Cochin boys had pretty decent combs and wattles by 9weeks.
