I do roughly 40% oats, 40% barley, 10% seeds, 5% complete dog food and 5% broken dog biscuits. Mine did eat the pea flake but not a whole lot so I stopped buying it and it hasn't made any difference to the quality of the mice. When I got my rats I got given a bag of food which was the Shunamite diet. I fed the rats on it dutifully and when it ran out they got a modified version of my mouse mix. Their coats improved rapidly and within 2 weeks looked much healthier. That mix had garlic and kelp powders in as far as I know and it seemed to harm rather than good. I'd leave them out if I were you.
