I just moved my 15 yr old 16 hand Quarter horse to a new barn and was told horses get fed 3 meals a day. This past weekend I found out that the last meal of the day is fed between 2:45 and 3pm. I'm worried because I don't think it's good for him to be without food for 16 hours. The first feeding is at 7am. The barn feeds mostly cubes & pellets and a very small amount of grass hay. I picked up a bag of grass hay pellets to give him a snack (about 3 lbs) in the evenings when I visit him after work. Is it safe for him to go that many hours without food?
