I don't have rabbits but this is what I think.
I think that they shouldn't be in cages since it does not provide nearly enough room (even big ones) for them to exercise and explore. Rabbits are much like cats, though they don't play fetch like a dog they do need plenty of space to run and play. Hutches are also small and have the same problem, and the heat and cold can hurt them. They are also vulnerable to predators out there, even if the animal doesn't kill them it can give them a heart attack and they'll die.
I'm working on an article about them and here's what I have so far on cages and hutches
The Problem with Cages:
Can you imagine putting an energetic puppy trapped inside a cage he could only (barely) pace back and forth in all day? Sadly, that’s what it’s like for a lot of rabbits. Often times they can’t even stand or hop around. Instead, they get depressed, and aggressive from pent up energy and fear from lack of bonding. Rabbits love to run across the house, and have hiding places, and explore in a safe environment. These small do not provide nearly enough space. Not even a fraction of the amount of space needed.
The Problem with Hutches:
Rabbits can become very overheated in summers, get too cold in winter, and in storms or bad weather. They are also vulnerable to any predators that might be in your yard. Even if you don’t think you have them, they’ll know when there’s a rabbit they could eat for lunch. A lot of hutches a snake could get through, or a raccoon could open, or a coyote could tear apart. Even if they don’t get to the rabbit the rabbit could die from a heart attack. And, like cages, hutches just don’t provide enough space. Even the ones with multiple stories. They need room to run in, and they don’t really like being up high. Though some people let them outside of the hutch to play they could get picked up by a hawk in a heartbeat. No matter how big you think your rabbit is, hawks can carry away even small dogs. Though you can let them outside, it needs to be in cooler weather under close supervision for short amounts of time a day.
If you free roam them inside a bunny-proofed house you can bond with them, they're safe from harsh weather, safe from predators, and they'll live a much longer, healthier, and happier life. You can look at Lennon The Bunny on YouTube. Lorelei, Lennon's owner, has a bunch of great info on free-roaming rabbits, grooming, training, supplies, bunny proofing, and much more.
I don't know a whole lot on raising rabbits for meat, but I would at least avoid keeping in small hutches. If you can build an insulated barn that you can free range them in, and let them have supervised time outside, that would really benefit their health.
I love rabbits and other animals, but I do support raising them for food. When buying meat, I would want to be sure that the animal had a healthy life.
