Well, I'm going to try and make my own kibbles for my crabbies and I'm not sure what I need. I know I need a source of carotene, grain, protien, omegas, calcium, and iodine. Am I missing anything? If so please let me know. I want them to have the best diet possible. I'm not looking for specific foods, but the different types of nutrients and things that would need to be in the foods. Thanks for your help!
