Good grass hay and pasture is usually what donkeys enjoy to eat. If the hay or grass is grained, the protein is best to be lower than 12%. However, if a donkey is overfed, it will have a "roll" on the neck. A roll is when fat bunches up and stays in a part of a donkey's body, and they usually happen on its neck or its hip. If they develop on the donkey, it will usually stay for its whole life. If the neck roll of fat gets too heavy, it will fall or "break over" to one side and never recover its balance again. This is why donkeys should not be fed too much. Many people do not like to work with donkeys. They think that donkeys are too stubborn and will kick them. However, a donkey that is nicely trained can be as easily managed as other horses.
