My Finn and Lara get variety of veggies like lettuce, cilantro, parsley, basil, cucumber, carrot, celery, kale, grass, dandelion, apple, blueberry, and etc. Out of those, lettuce, cilantro, basil, parsley, grass, cucumber, dandelions, celery, can be given everyday. Others including carrots, kale, and various fruits should be given with care, and in rotation so not everyday.
My Finn and Lara get endless supply of hay with some pellets. They get three meals of veggies a day.
