Where can I get animals for the farm and how do I feed them?

You can buy animal buildings in the Shop (the store icon is located in the lower-left corner) in the Animals tab. You unlock different types of animal buildings as your farm level increases.

To make animal feed, build the Feed Mill. Bees and bombyxes are an exception. For them, you need to plant Honey Flowers and Mulberry Bushes from the Plants tab in the Shop.
