The "blue" offspring is likely the result of recessive white in the white rock cock/erelJust posting to say hi!
We have some White Plymouth rocks that i'm considering breeding. They are quality bred stock. I think I'm just a little overwhelmed trying to figure out what I'm doing --- doesn't help that my girls don't seem to want to cooperate with me either --- only 2 of my girls are laying.(out of 6).
I've got some Partridge rocks too. I thought about breeding these ones, but trying to get 'perfect' feathering seems almost impossible. I hatched some eggs of Partridge hens and a white roo and got some beautiful blue girls.
