I've been trying to figure out what gender this chick is. It is about 4 weeks old. He/She is one of my biggest but is also a few days older that the others.

what breed?

I don't really know. It is mixed. Mom is a game hen and dad is either my leghorn or RIR. haha. This one and one other are the only yellowish white ones that she had. All others were reddish. This one has blackish feathers on it but the other one is mainly all yellowish white.
