Quote: You may be right Carolyn (if he's a feedstore bird), BUT, he could be a true Am if he was crossed from different colours, thus producing the "Splash" coloration he has. From my understanding, splash is crossed with black to produce blue. While recessive white is the diluting gene reducing black to blue. So you need splash to produce blue (which doesn't breed true).
If I'm wrong about the genetics, I'm sure someone will correct me - Chickielady and I think Stumpfarmer have Splash cocks for breeding blues.
