All your diet seems to be good. It looks like you've done your research. I too supplement my yearling and the baby Uro with calcium supplement at least everyday and multivitamin 3 to 4 times a week. Note: I only use little pinch of multivitamin and calcium supplement as too much supplement is even worst than too little. I also provide them with high protein food like parsnips, peas, and lentils. I buy frozen peas from supermarket and thaw it out in a strainer under running hot water. Before I serve the peas, I mash it a little bit with the fork, so they can digest them better this way. I've seen some ate whole peas and passing them through whole. That's why I suggested mashing them first. For the lentils you can serve them to the Uro the same way it comes in a bag. I just put some dried lentils in a little dish for them to snack on all day long and my Uros pick at it all the time. For the parsnips, I grate them on a cheese grater which seems to get it into the serving pieces I want, and it easy for them to eat. You can use vegetable grater that is part of the food processor if you like. That would work, too.
