About FeedFeed is purchased from the game at $10/day or set boarding stable price. Horses must be fed to breed, train, and show. Horses without feed will have the feed icon beside their names on the stable page.
Purchasing feed is located on your horses page under the "Edit" tab. A horse must first be boarded to buy feed. To buy feed input the amount of feed desired in the "Purchase feed" button. Complete the purchase by clicking the "Edit horse" button at the bottom of the page.
Feed storage now works! If your horse is boarded at your stable, you can set it to feed from storage. You can still feed it like regular but if it is set to eat from storage, feed will be reduced from storage instead of from the horse. If your storage is empty, the horse will have feed reduced like usual.
The benefit here is that horses “auto feed” from one place and as long as you keep your storage full, you don’t have to feed your horses.
