No Temple, that one is a new one for me. I guess I would tell them that all of my Ameraucanas are Rust exempted. I have never seen a case of rust on any of my birds. But, wow, telemarketers can be a pain! The one that one that I get most is the guy that says he is calling about my windows. He has such a foreign accent that you can't hardly understand him. If you let him go on he says he is calling to fix my Microsoft windows. Now, before he finishes about calling on my windows I butt in and say "That's fine I already have windows in my house, Goodbye" or " I have Anderson windows". I have even went so far as to say 'Whats a computer, I don't believe I have one of those" Some times he hangs up on me and some times I get the privilege!
