I am in the process of building another coop for the roosters and I got saddles for the hens. If I house them separately, are they able to interact together in the yard or do they have to be separated at all times?
I'm re-quoting your original post so I can address your primary question. Yes, it's possible to house the boys separately from the girls and still make it possible for them all to interact.
You've pretty much agreed that a bachelor coop is necessary to take pressure off the hens. When you go about designing it, try to design their bachelor pen to have a common wall with the hens' run. Roosters very often are quite content to interact with the hens through a fence barrier. This has worked for me for years, and I saw no downside from it.
When I had more than one rooster, I would alternate days that one roo could free range with the hens while the other remained penned up. That way, each roo got his chance with the girls, and the girls were far better off. Although, you may find that even one rooster allowed access to three hens may result in over-mating. I would then restrict access to perhaps one day a week.
You can have your pet chickens and manage them well, too.
