Hens or Rooster (Americaunas)? Need help!

[DustyChickens]

I've had these chickens for about 5 months now. I've noticed that the two red colored chickens have mounted the other chickens. I had one rooster that I ended up giving away. Any advice on which may be pullets or cockerels?

First two birds are roosters, last one is a hen.
