I bred my Whites Leghorn hens with my Black Australorp Roo just to add to my flock. I also bred the same Roo to my silver laced Wyandottes. So after incubation I discovered the WL and BA crossed chick's would be called Austrawhites and someone asked if I would sell them and told me they even though they are crosses, they are "Pure bred Austra Whites". I'm really new to chickens and have little knowledge on genetics nor am I familiar with many breeds. Can anyone clarify for me? Also, what's the importance of only having pure breeds? The interested buyer got a little judgmental because I had crossed my wyandottes with the australorp. Said only pure breeds should be bred... the same fellow that wanted to purchase the austrawhites... lol. Help??
