Are they roos or am I mistaken - my first attempt at sexing

[Eggs-Actly]

These pics were taken this weekend when I put the babies out in their new coop. I need your help because I cannot have any roos where I am located and am afraid I have at least two roos. Have a look and let me know.

Here is pic one. The two in question are the two buff orpington's (one is on the right and the other on the left in the background)

Here is pic two.

I hate to say it but they both look roo-ish compared to the other ones in the pic.
Do you notice their legs looking thicker than the other chicks?

That last pic looks like a roo.

Ok that's what I thought - two roos. The good thing is that I'm getting better at this

. The bad part is I have a find a new home for them.
