I once kept a couple doe rabbits and one buck. I tried to only breed the does about eight weeks before Easter, so that I could sell all the babies as Easter gifts for kids, which would pay for the whole years feed because mostly the rabbits ate the yard. It's ridiculously easy to keep rabbits, and if I allowed the does to breed 3 or 4 times a year, as they can, I would literally be unable to eat all the offspring. That's like two rabbits a week, and from only two does.
It would be incredible if there wasn't room on that quarter acre for three rabbit hutches. Still, rabbit is good food, but I don't think I'd want to eat only rabbit for the rest of my life. A half dozen laying hens produces >3 eggs a day, more like 5, and that's an awesome source of food - and they love to eat garden pests, so there's your integrated pest management right there. Chickens are even easier to keep than rabbits (except for noisy roosters. The neighbors rooster seems to think 1am is a good time to crow lately) and don't take any more room. I prefer chickens because eggs are like, the perfect food, but rabbits are a close second.
