Are they roosters?

[lovesfarms]

I got 10 (supposed) female Americauna chicks from tractor supply. At 5 weeks one has a bright red comb and crows (the white/black one). If I don't miss my guess I may have 6 more roosters. Can anyone help me with these pictures? I can't have roosters and I don't want to keep them any longer if they are roosters. They are the sweetest friendliest chicks I ever had and it will be difficult selling them if I can't keep them. I spent lots of time and affection with them. Has anyone else had experience with getting a lot of roosters from tractor supply?

You are definitely right about the white one. I think pullets on the others though.

Same, I think the others are pullets.

Thank you for your answers. Some have such huge feet and bodies while 3 of them are just half that size. All 10 of them feathered very quickly including the rooster. Their is a significant difference in weight. They fly from the ground to my shoulders and I can tell which one it is by the weight. I will add another picture of one that seems very boyish and see what you think.
