This is my buddy's chicken and its about 7 months old. It's really big compared to my full sizes RIR hens, and white leghorn. So I thought it looked like a barred rock/white leghorn cross. And I think it might be a rooster because it stands its feathers on its neck straight up sometimes when it tries to fight the white leghorn hen. But there is no crowing or anything yet, or even a bright red comb. So any ideas of what breed/gender. Thanks
