So that takes the cage number from 2-3 to 6 or more. If that is the case, I don't think I have the space or money/materials to have or make that many cages.
4 cages...tops! And you can actually build your own and even pick up some factory made ones for free or cheap in the local classifieds! People get a cute bunny for a child and often will sell the whole shebang for cheap or give it away "to a good home" for free. I've seen this numerous times.
If building your own, you can build your finishing cage to be adaptable for several situations. My finishing cage was just two cages suspended side by side, wired together, with a door flap cut out in between. I put food on one side, water on the other. This gives bunnies something to do and builds nice meaty haunches during this finishing out time. Little chicken wire hay racks wired up in one corner of each cage makes for little hay waste and prevents having wet, dirty hay on the cage floor.
Container gardens can be built right along the bottom and attached to your kennel/pen. They can consist of scrap lumber(seconds from a lumber mill costs about $20 for a huge bundle) designed like a big, long box.
Using the square foot gardening method, vermicomposting and utilizing your manure....heck, you can raise quite a little food station! Note: Might want to place a nice little panel between growing foodstuffs and chicken beaks/goat noses!
You can use hardware cloth for this. You can place plastic from the top of your kennel, slanted like a leanto down to your containers for starting seedlings and even growing greens in the winter....this will block wind from your livestock and create a source of warmth as well.
Vermicomposting leads to another income stream...worm sales. Also another food source for your chickens.
If you use the hardware cloth, you can have vining plants in your containers, growing small winter gourds/squash that can then be fed to your livestock later on. My sheep simply love cucumbers, squash, gourds, pumpkins. If you grow the little pumpkins, be aware that the seeds act as a natural anti-helminic for your goats and chickens.
The whole shebang could be mounted on skids or wheels for ease of moving and could even be moved with the car.
