Im wondering if this baby is pure barred rock. I got some fertilized eggs for my broody hen to sit on. The eggs were from a coop of only barred rock roosters and then a mix of hens(barred rock, Plymouth whites, RIR, and a couple others I can't remember). They're about 2 1/2 weeks old now. This one I believe is a roo due to the developing comb, and the light color. But mostly I'm wondering if he looks to be pure?
