That will work.Fluff and feather legs but for ee that's ok.I used hatchery barred rock cock over black and blue ameraucana hens.Third generation and some fourth generation in the incubator now.Mine are a serious effort to create a cuckoo ameraucana.Barring creates spotted legs with slate but some have slate legs.I expect to get more slate legs each generation.If you would like to join in on a serious effort I could share eggs/chicks next year.I will have to get some new pics to post.Take a look at lavender cuckoo thread and barred ee threads.Some said slate legs with sex linked barring was impossible but I had my doubts.Difficult yes.Once the right genes are in place I think it will breed true.Where do you begin? I've been told my LF barred cochin is a cockerel. Could I cross it to my white pullet above and get some very fluffy bearded EE?
