Well, you could just keep them in separate cages and all next to each other. Also are you going to APA show or like a county fair?I'm hoping to show my three girls who love to be together. I'm considering keeping them all together in a double coop for the show.
Also showmanship is a contest where the judge tests the handler and how "tame" the bird is. There are nine steps, which I'm bad at explaining how to do, and the order of them.
