All you can do with it is either leave it in your bag, or put it in your cart/storage box(the one in your house) If you put it in your cart/box, then the feed will appear in the feed bin inside your barn/coop..
Yeah, it's sad they took out the animal food bins for this game. They barely need feeding once the pets do their jobs. Fodder and chicken feed and pet food taking up bag/storage space is pretty lame. --- ~*~Sin~*~Sinistral of Chaos~*~
