Have had QH's my whole life so we are new to miniature horses. Asked my Purina Rep how much hay. It seems like such a minimal amount but I do realize the body size is quite different. How much hay is recommended? Right now we are weighing out their hay on a scale so we don't over or under feed per the Prina Reps advice on weight of hay. They are on dry lot so they are soley dependent on hay and grain. We are feeding excellent Brome and Orchard Grass mix. All advice is WELCOME!!!!
