12 Chickens

If I could own a horse, cow, or a dozen chickens, I would choose the chickens. I would because you can eat them. Slaughter them and make a nice stew out of them. You can grill them, or fry them. If you dont want to eat the chickens themselves, you can always collect their eggs and eat their eggs, without getting rid of the chickens. Finally the last thing you can do with them is breed them. Doing this will get you even more chickens. Then you can sell them and trade them, and eventually get a horse from someone else. Choosing the chickens allows you to get all of the benefits both of the other options give you, but with more flexibility with what you want to do them.
