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.
