My 2 yr old beardie Norbert has never been thrilled about eating his veggies. He'll eat them rarely although I offer them every day. Oddly enough he will chow down on clover if I set his on the ground in the yard outside but I know it's not good to let him eat wild plants that aren't grown in a controlled setting. Any tricks or advice on stimulating his appetite for veggies? I've tried a huge variety but it doesn't seem to make a difference.
