A couple or three months afo I started a thread about putting my rabbits in a colony pen. Today, I'm declaring my experiment over and a total utter failure. Not only do I not have any kit, 3 rabbits ( 1/2 my herd) have flown the coop. A few days ago it was 2 of my Flemish Giants, today it's my californian. I have no idea how thay can get out. They are either climbing 6 feet of fence, squeezing through the 1" chicken wire I have reinforcing it, or waving a magic wand and teleporting to the other side. There is some digging in the pen, but no tunnels under the fence. The fence is buried about 10", so squeezing under is an impossibility. I hate to put them in cages after giving them a taste of freedom, but this is supposed to be a meat producing program and I'm further behind now than I was 6 months ago. I still think the colony system has a lot of merits, but only if done inside a secure building.
