Ok thanks. It's good to know who's birds came from who. I'm already familiar with Mr. Housley, and for Don, I've read about him in Tomas Condon's thesis.
That website has very useful pictures to show what pure birds should look like, but it also has pictures that include chicken-crosses without telling the reader which is which. Those unfamiliar the with what the species should look like may learn the wrong characteristics - like I did a decade...
