Improved livestock feeding devices comprise a container suitable for storing feed such as, for example, hay or grain and an extension portion surrounding the container. Generally, the extension portion has a shape that defines a plurality of separate eating stations for the livestock. In some embodiments, the extension portion can be an undulating extension having a wave-like shape comprising regions of increased extension and regions of decreased extension. Due to the presence of the extension portion, livestock such as, for example, horses can be separated during feeding which reduces potential injury and/or eating interruptions that can occur when livestock use existing feeders. Additionally, the extension can have a shape adapted to collect feed that falls out of the mouth of a feeding animal, which can reduce the amount of feed that contacts the ground surrounding the feeder.
