Do you have anymore specific questions? You can raise lots of stuff on the amount of land you have. You could have a whole little herd of Nigerian Dwarf Dairy goats, or just a couple of full sized ones. You will to be prepared to provide all their hay and grain since they won't have much acreage to graze. Rabbits are extremely efficient at making meat in a small space, and quieter and more unassuming than even chickens. Don't know anything about pigeons, but I did have a chain link run where I kept a couple of chickens, a pair of mallard ducks, a pair of nigerian dwarf goats, and a silly half-blind rabbit. They all would get out and free range together and did just fine.
Add that to a good square foot garden, and you are in good shape.
