I was wondering how to start a line of broken new zealands. Do I have to start with NZs that already have a broken color? I'm new to this but I assume that its not as simple as breeding a red to a white. But that being said, broken color patterns came from somewhere... how far back up the chain of crossbreeding could I go to get that pattern? Or do you recommend buying stock that already have that color pattern? And if so does anyone know of anyone that has any for sale?
