Every week I prepare a large tortoise salad for my two Russian tortoises then stick it in the fridge and give them portions of it every day. Every week I change up what the salad consists of just to make sure they have some variety to their diet. I was wondering if it is okay to feed my little guys the same mix of greens for a week and then changing it or if this was not enough variety for their diet. For instance, this week their salad consists of a red lettuce mix, mustard greens, a little bit of shredded carrots, boy choy, endive, broccoli rabe, kale, cilantro, and a little bit of Romaine lettuce. Sometimes I also sprinkle it with ZooMed Grassland tortoise food too. I also offer some fruits or berries once a week, as well as sprinkle their food with calcium once a week. I just wanted to make sure that this method I am using is best for them and if not, then I am open for any suggestions. I just want the best for my little guys!
