I have had the very same thoughts (except not about fish) -- Yes I think rabbits might work-- for me rabbits and chickens would be equally hard... We just acquired 2 acres and I was thinking to have a few goats and maybe pay or exchange some meat in return for the neighbor killing a goat for us (he raises broiler chickens and lambs for slaughter so i know he could....)-- Also How about guinea pigs -- would those be easier? ...We have 3 dogs and it does seem a shame to not utilize the land we have to raise food for them vs buying it in a bag!
