I figured. The blue pullet that came with my Privett birds and one cockerel that I'm pretty sure is carrying the blue but is coming out mostly black, they are both bigger than the rest. All the rest of the black cockerels are maturing faster than the one, too, and he's got a different personality. He's not flinchy like the rest.
I really want to just focus on NN's, but it's so difficult when there's other breeds I really like, like the Australorps.
The Blues can come in different shades of the blues, depending on the color of the parent. Are you planning to start breeding some of these?
