Animals produce the products needed for production and orders. They can be bought in the market after you have purchased the farm for this animal.
In order to start production, the animal should be fed. Click on the animal farm to drag food to the location or start producing it by clicking on the magnifying glass on the window with feed. The yellow arrow will show you where you can produce food.
The animal and its food can only be placed near the animal farm.
The animals can give a limited number of products. When the animal resource is out it turns into a golden trophy.
