Seen where a few of you decided to start rabbit colonies in a fenced in area, instead of going with the traditional cages. So I had to give it a try. After losing another batch of 8 kits, I decided it was time. So I got a nice 40 by 40 foot area cleaned off and fenced. Built a small coop for them to use if they wanted, and set them free! After a week, the rabbits seem to be happy as larks at their new found freedom. The rabbits have really taken well to the pen idea. I know my girls love it. They can stand outside the pen and watch the rabbits hop around or run, or they can go inside the pen, where their favorite rabbits will run up to greet them and let them pet them. Not to mention the girls have them eating out of their hands. So far I give it 2 thumbs up!
