Been here done that! And will never do it again! It is a slow process that takes a lot of work. Keeping them separate but, you have to have then in a place were they are side by side but can't get at each other for a couple weeks. And then you wait until night time and put them on the same roost together. And then the pecking order begins. You have to make sure they are letting everyone eat and drink. Then leave it to mother nature.
