Pullets or Roos? 6, 5 and 4 week old chicks (are they really EE, Brn Leghorn & BRs?

[pinkaliboo]

I bought these chicks from our local feed store. I have uploaded 2 pics of each one. The first one I was told is an EE, (6 weeks old) which I bought with 2 RIRs, One of the RIRs died the next day. I went back and got the one in the 2nd picture, which I was told is a Brown leghorn (now 5 weeks old) then my last RIR died. So, I went back again and got the 3rd one, (now 4 weeks old) which I was told is a Barred Rock. Thus the different ages. I cannot have roosters where I live, so I am hoping I have all pullets. I don't want to get too attached to the "girls" then find out I have a rooster. Any help is appreciated!

I just realized the 3rd pic is of the EE, not the leghorn

the ee and the leghorn looks like pullets the last could be a br, if it is I'd say pullet by leg color. But leg color is also why I aint 100% sure its a br, a bit much on the wash that a br hen normally has.
