Don, why not post this in the forum so ANYONE who has the black copper & blue copper birds can know your advice? I guess I don't understand the need to be so secretive. Please do share what you believe to be the best way to go about this. (I do not have anything other than Black Copper, but I am definitely interested in hearing, as this could benefit other breeds as well.)
I do know that Don really doesn't like confrontation. He doesn't try to start arguments and he doesn't enjoy participating in them. He has his beliefs and states them simply.
He wants to help others, not start heated debates. Hence, he does help folks via email. I am positive that he would share his advice via email to anyone who contacts him.
Normally, if he says he will share something via email it is because he wants to avoid additional hostilities from other posters.
