Sexing Am Game Chicks? Color questions too?

[ReefRanch]

These are 3 of my 15 Am Game chicks I got at an auction. I was wondering how to sex this breed? I have never owned this before now. I was also wondering if anyone can post pics of what these colors or patterns grow up to look like. Sorry the good pic I took will not upload. Can anyone tell the colors by this pic? The one on the far right is yellow with a redish hue, the middle one is brown with dark brown marking out lined in black, and the one on the left is yellow with brown, black marking and a blueish tent.

Bump! Please I have 15 of these little things. All wings are long, short, long, short so if that method works on this breed they should all be girls. Im which case I would be looking for a Roo to go with them and mom. But if one or more is a roo then I don't want to buy another as the males of the breed are known for hurting eachother.

Also got them from an auction so if they do not look purebred Games please let me know what they may be xed with.
