Roos or Hens?? - Ameracauna

[Forever Green]

I bought this flock (day old) from a local hatchery. They were sexed as all hens, they are 8 weeks old today. I know my one Ameracauna is a rooster, he crowed very young (dark head, some brown wing feathers, maturing comb). However, my second Ameracauna, never crowed until today. I saw her/him crow this morning for the first time, very raspy, but was trying hard to crow like the known rooster Ameracauna. Is it really definite crow means rooster? I really wanted hens, but I love these birds and so far the entire flock is really happy.

See attached picture - 2 Jersey Giant hens, 2 Aracauna hens, 2 Ameracauna roos (furtherest to the left -silver, known roo behind)?

here is a better picture of the 2 Ameracaunas in question:

those are EE's not Ameraucanas, they don't meet the color standards.

Thanks for the feedback, they were sold to me as Ameracauna from a local hatchery. I know the one with the brown feathers is definitely a roo, any thoughts on the other?

both roos if you already know the one with brown feathering is a roo.
