Trying to breed Blue buff columbian orpingtons

[phillip0104]

I used to raise these in Florida but the farm i got them from as far as I can tell doesnt have them any more. I currently have blue orpingtons, buff orpingtons, silver lakenvelder, and am about to get some columbian wynadottes. Could anyone put me in the right direction how to start the process. Ive been raising chickens for a decade but I've only ever had a roo of this breed, So this is not my forte.
