Definitely a rooster. This is just a guess, but it looks like he could have one parent a Silkie/Polish, and another parent a D'uccle of some sort. Probably the polish was frizzled.
Not saying there is, cause you cant ever tel with mixes, but it's mostly the way the bird is shaped, looks exactly like one. The feathered feet, too. Although, the silkie could have given it that.
