The convenient 5-Gallon All-In-One Hanging Deer Feeder from Moultrie includes a collapsible plastic bucket with a programmable feeder kit that's a breeze to set up. Just add batteries and feed, then find the perfect place for it to hang. A tapered hopper with a collapsible design saves on shipping costs and shelf space, while a built-in funnel keeps feed from collecting on the bottom and sides of the bucket. This feeder requires just 4 AA batteries (sold separately), making it a great option for backyard feeding. Feed should be around .25 inches in diameter or smaller on its longest side. Whole, clean kernel corn is recommended. Corn mixed well with soybeans or protein pellets can be effective; however, mixing could cause clogging depending on the ratio of corn to the additive or type/brand of the additive.
