My oldest son has been wanting to build one of these for a while. I took a little vacation time to wrap up some things around the farm and this project was on the list. It’s a hare pen. It measures 6’x3′ and is 24″ tall on one side, 18″ tall on the other. 3/4″x1″ slats are screwed to the bottom on 3″ centers. That’s as much of a plan as you’re going to get anywhere. This is enough room for 8-12 rabbits.
The roof is covered with three scraps of metal we found out back. The two on the ends are nailed on, the middle one is nailed to a couple of boards to give it weight but floats freely and is easily removable so we can load and unload it easily.
At least 70% of the floor space is open to the ground. The rabbits are free to graze to their heart’s content, though they also have access to pellets. We move them a couple of times each day, leaving their manure behind to add to our fertility.
Here are a few links I used to put together my own hare pen. I have fewer ribs than the original Salatin pen but it seems to work fine. My kids can manage it on their own.
