The 3 amigos?

[Jules929]

The options are EE, OE, Blue Isbar, Ameraucana. At least one is starting to crow. They all have feathered legs/feet. They are now 17 weeks old. I need to post the cockerels on the local chicken group site, so I am requesting your help to ID the breed/type and confirm that they are all cockerels, please and thank you!!
#1 has pea comb and muffs:

#2 has a single comb:

#3 has pea comb:

From left to right #1, #2, and #3

They are all Olive Eggers. Ameraucanas x Marans.

All are crossbreds very possibly Olive Eggers as @Brahma Chicken5000 stated. Could also be Easter Eggers or simply crossbreds. 1 & 3 are cockerels, I think 2 is a pullet.

3 looks like a cockerel to me... and maybe 1. I am not very good at identifying breeds, sorry.
