If you want to tame animals, you need to get the certain house first. Every type of animal needs its own house.
Chicken Coop is available in Store, while houses for other animals are already placed on your farm and you need to unlock and repair them.
With each subsequent upgrade, you will be able to tame one more animal using the house.
If you are struggling to find the required house, open the Farm Store, go to the Animals tab and click the Find button. The camera will automatically move to the respective house’s location.
