Thanks! I printed that off! I had been trying to think of some way to do something like that -- now I have an idea how to do it. I think I'm going to make chicken-wire cylinders and coat them with cement (ferrocement), then build lids.
Great find. I read Rabbit Production and they had one picture in there for a rabbit dome. I searched for a long time and never found one online. I would love to do something like this. I'm reading this at work tonight.
I've been wondering about something like this myself. But I keep running into the fear of fireats invading anything placed underground. I know there are poisons, but I don't like using any if I can keep from it. And ants could devastate a nest box of babies before you knew it.
Another thought, before we start moving the earth to accomodate these underground cells, have you thought of experimenting with insulated boxes within boxes? Utilizing woodshavings or something for stuffing the cavity between the boxes? I know that leaves out the cooling effect of ambient earth temps. But if I have to mound up earth anyway, I've lost most of the effect, right?
Gives me a lot to think about, thanks again for sharing.

Halo, ants have moved into MY house overnight, more than once. They are as likely to get into an insulated box as anything. Right now my cages are suspended from a framework with wire to thwart the ants and that seems to work. I'm thinking on how to protect underground cages from them.
I believe in God's willingness to heal.

Thankfully, we don't have fireants in my location. We do have other pests, but if the underground dens are cement that will stop most of them.
Our place is pretty flat, so mine will have to be above ground and bermed (which will still have most of the advantages of being under ground, but less likely to have drowned kits in our Oregon winter monsoons). I've got some RR ties -- I think I'll use them to support the earth at the back of the underground dens, and the supported soil can be garden beds. Then put worm bins under the wire cages. Multiple-use is good for people with small spaces. (I'm trying to think of a way to integrate the chickens into this, too, LOL!)
If I remember correctly about wild rabbit nests the tunnels are built to withstand flooding... so where they have the babies it is a higher elevation than the rest of the tunnel structure. I wonder how this type of structure can be modified to immitate that. Mother nature is ingenious and would take care of the flooding problem if it is an issue in certain locations.
I'm bumping this thread because there's a good article over at SurvivalBlog ( http://survivalblog.com/ ) on building underground (or aboveground) den traps, and I though some of his ideas might be useful for our underground rabbit dens, as well.
Behind my doe in the picture is a five gallon bucket. It is attached to the cage via screws on one end and another five gallon bucket on the other. I linked 5 in a chain. I drilled holes in the bottom for drainage. I buried them. So far its working well. The cleaning is becoming a problem as this doe will not do its business outside. Nothing a garden hose and time won't correct. Next one I'll build some access but this works for now.
