Hi All, I have question. I have 2 Barred Rocks, 2 RR Reds, I black Astrolorp, 2 Golden Comets and 1 White Rock. My question is this. They are all the same age about 5-6 weeks old but the white rock has a very red and quite large Comb and waddle already while none of the other pullets have anything but a very small slightly yellow or orange come that you can barely notice. Is it that white rocke develop quicker or is it that the white rock could be a roo. It has Huge legs as well.
