I want to get my sons into 4h. Their young so the only animals they can do is rabbits or chickens. I don't have the breeds they allow so I figured we would try rabbits. I already have 2 Dutch rabbits. Their sisters and I saved them. Their not the friendliest to the kids. A little scared. I was planning on getting California rabbits for meat pens. But I have some questions. 1. His big does the hutch be? 2.Do they need space to run? 3. Can I place more than 1 rabbit in each hutch? Do they need nest boxes?
