My 3 roosters all get along fine and I started out with a Thai, then got an EE roo, then a bantam Ameraucana. I did nothing more to introduce each one than put them in the yard with the flock. I've never had a problem. I've told this story a few time on here so I hope it's not getting over read but in the past they all three joinded up and formed a little rat pack. They would ditch all the hens and hang out in a corner of the yard together. Until I got a bunch of bantam hens for the bantam roo, now the pack has not been seen together since.
Also I've seen my standard EE roo mount the bantam hens. The poor little b. Ameraucana has to just stand there and watch
