Animals are a pain. They take up space and they do not give very much money daily. A Single apple tree is better than 2/3 of the buy-able animals, and draws with the last. Sheep cost 700 coins. In theory, you can buy 2 apple trees and then gain twice as much as you would from 1 sheep! Trees are much better than sheep – it appears.

However, if you find the animals or they are gifted – you may as well! I would suggest not letting them wander…

Also, helping animals that wander onto your farm can give you a small amount of money. But it is up to you.
