I was kind of making this as I went, but after working more in the space, this is pretty much the eventual plan of action. I'll post pics as it comes to fruition. Really need it up by end of the weekend, so a busy one. E. through I. may be added a little after the weekend, instead just using existing watering and feed methods until then.
Basically, this was a standard 12' x 12" horse stall, until dividing it up.
A. Stall Door (wood with chain link window)
B. Individual habitat door (2x4 frame with chain link)
C. Individual habitat door (2x4 frame with chain link)
D. Individual habitat door (2x4 frame with chain link)
E. Water stations (Inverted 2L bottle with drinking nozzle, in wood box with plexiglass panel in front (so you can see water level). Hose runs along top boards and down the wall support (a wire wrapped hose).
F. Feed stations (Large PVC pipes with quarter elbow at bottom and top cap, to form gravity fed feeders)
G. Feeding platform (Plywood with 2x4 legs)
H. Ramps (Plywood, hinged to fold out of the way (and allow for easier cleaning)
I. Burrows (Plywood, hinged on top for easy cleaning, cut out burrow hole)
J. Floor area in each habitat
K. Stall Windows (chain link)
L. Walkway area (no rabbits here)
Walls are all 2x4 framing and chain link fence
Ground is clay but with wire mesh, then dirt and shavings on top of the grid (prevents them from digging out).
Chain link basically because this is what I have. I'd prefer to use 1 inch mesh, but expensive. I'll put a strip of the 1 inch mesh along the bottom of the chain link, just as a precaution (and to help in the event of any desired breeding).
Also has two fans to help keep the stall cool when it's really hot out. (one blows in from front window, another blows down from the rear top of the stall). The chain link windows and walls help with both light and air circulation, but the stall itself (as in the stable) is nice and weatherproof as well, so even in a bad storm, they'll stay nice and dry.
