Sheep

Overview
Sheep are passive producing animals that produce a steady profit. Sheep produce wool which can then be transformed into wool bundles by the use of Spindle machine which is purchased in the animal section of the build button. Sheep are similar to cows due to the fact that they both require a bit of time to harvest their materials but are mostly passive animals.

Money
Sheep produce wool pieces, and once you collect 5 of them, you can use the spindle to turn them into a wool bundle, which will give you 2,500 coins each. It takes about 90 seconds~ to shear sheep again. You will need a shear to shear the sheep, which costs 2,750 coins. The spindle mentioned costs 3000 coins.

Costs
To start farming on sheep you will need: a Spindle for 3000 coins, a pair of shears for 2750 coins, a Small Animal Trailer (Not advisable to buy Medium Animal Trailer) for 5000 coins, one sheep for 3000 coins, an Animal Feeder for 3000 coins, and a box of Animal Food for 450 coins, (you will have to buy animal food periodically to restock the feeder) or make Animal food via Animal Food Factory, all for a total of 17200 coins. You will have to buy fencing for the sheep, but I do not count it in, as pricing will depend on how large the fence is.

Trivia

 * Sheep is the second animal a smart farmer would want to invest in, with chicken being the first.
 * Sheep are the latest animal.
 * Unlike the cow or chicken eggs (for cows you need to send them into a barn and click a button called 'Milk cow' and a jug of milk will magically appear. For chicken eggs, when the coop has at least 12 eggs in it, click a button called 'Collect Eggs' and a box of eggs will spawn or more if there are more eggs reserved.), the Spindle actually has a animation of it threading the wool piles into wool bundles.
