Total nutrition for my garters

[boyer45]

I have read a lot of great posts about what a good diet is for garters but I still have questions. I also thought (maybe?) a new thread would be helpful to get all this info in one place. I have read a couple articles(online) about mice being complete nutrition but I have also read here that mice are just a part and should be supplemented with fish and worms.What is the most complete diet?When should I use calcium or vitamins and how do I mix the right amount?How do I administer them? Do I put it on their food or in their water? Thanks in advance for your help!!
