I feed locally milled pellets - the breeder formula to all of them. Higher protein, I wasn't sure about the protein content in the regular feed. I get a mix of alfalfa and grass hay from a vendor at the market. Supplement with dandelions, carrot tops, occasional lettuce, and whatever else I can forage for them. Apple tree leaves are a favourite, they even like eating the little twigs and stems. I do give them treats, too. I cube and dry the ends of the bread(no one eats the crust), they also got to try prickly pear cactus fruit(that went over well). I have a baggie of unsalted pretzels that I give Lily occasionally(she's obsessed with them). Craisins, cherry raisins, and dried plantains are a favourite. BOSS obviously goes over well... Basically hay and pellets are their main foodstuffs, but they get lots of variety and tasty tidbits.
