What breed of game chickens do I have

[ezell5]

So my uncle gave me a bunch of eggs to hat he from his game chickens, he says they are grey game and something about green and blue leg hatch? I know nothing about game so I need help! I wanted to sell them but need to know what I'm selling and price to ask?!!
