All I can say is "Wow!" Copper looks like he might have some Marans in him... not that I know a lot about it, but maybe that explains the feathered feet? They are all beautiful!I don't own any CCLs so I know that's not a possibility. What I CAN tell you is that my (former) Ameraucana rooster wasn't pure but I've no idea what he was mixed with, and breeding him with some of my other breeds has resulted in some interesting offspring. Not only did these guys turn out crested, unlike their daddy, but they also have feathered shanks and one of them has 5 toes.
Here's a picture of daddy, named Copper. Notice that he's lacking the puffy cheeks typical of Ameraucanas.
Here are a few of his other offspring:
Monty, a Copper/White Rock cockerel
Senna, a Copper/White Rock pullet
Mags, a Copper/Australorp cockerel
Haley, a Copper/White rock pullet
Ziggy, a Copper/Dorking-mix pullet
And finally....
Harley, a Copper/EE cockerel.
He had some interesting genetics to work with.
