The first one is the Feed the Farm Animals. You need to feed three neighbor sheep, four neighbor chickens, and five neighbor goats. Once completed, you’ll be rewarded with 50 XP.
The second one is the Feed the Ranch Animals. You are required to feed five neighbor cows, four neighbor oxen, and three neighbor horses. When you complete this goal, you’ll receive 50 XP.
As you can see the two goals require you to feed your neighbors’ animals. The fastest way to complete these goals is to have a lot of neighbors in Frontierville.
Horses are somewhat rare in the game because you need to verify your email before you can unlock it in the Market. You’ll get one for free but the next ones will cost you 10,000 coins and four horseshoes. That’s a steep price for an animal.
