Are these 11 week old chicks pullets or cockerels

[lildevock]

I picked up 10 new chicks to add to my flock in February, as of today they are 11 weeks old and I am curious if anyone can tell if these three are pullets or roos. The Blue Andalusian and Lavender Orpington both came from straight runs and the Ameraucana was sexed as a pullet. With that in mind, the Ameraucana is by far the most aggressive chick that I have had thus far and she is constantly chest bumping all of the others. Thank you in advance.

From your pictures, they all look like pullets. By 11 weeks they would be showing some red combs.

Agree, pullets.
