Hello and top of the morning to ya! I consider myself fairly experienced in the world of chickens, but I do not know much about actual breeds. I am going to write the breeds I have down and I want you to tell me which are heritage and which are not. Lavender Orpington Buff Orpington Silver Laced Wyandotte Golden Laced Wyandotte Speckled Sussex Light Brahma Welsummer White Leghorn Black Australorp Partridge Plymouth Rocks. Thank you!
