Very interesting !
Base on family experience, I confirm that rabbits are the best meat to produce on a small scale. Very small space needed, very easy to deal with, so that's adapted to someone who ones little more than an acre of land and, as a bonus, it's much easier to have them taken care of by a neighbor when you're away than, say, cows. That's why many people own rabbits rather than cows or goats as pets. With rabbits, the only difficult part is killing them (look at them ! They are so cute ! And they love you ! Do you really want to put that knife through their throat ?)
Just one thing that bothered me : "Six to twelve chickens (with a rooster) will produce all the eggs (and then some) that a family would need." Well, you don't need a rooster if you only want to eat eggs (that's not true regarding milk from cows, lambs or goats). Of course, no rooster, no new chicken, but that's a long term concern (and one rooster might not be enough anyway, believe me, birds can be gay or sterile too).
