Crude Protein. When you're buying commercial bagged feed it's really all you need to worry about, the company does the rest. If you decide to try to make your own or buy custom bulk there's much more to it, you need to balance the amino acids (which make up the protein) -- but I assume you're buying commercial, yes?
Thank you. I wasn't even close with my guesses. The bulk of my feed is commercial (Dumor) which I have supplemented with those organics I got last month. I have several feeders so they can pick and choose what they like. Plus they get treats like peas and mealworms and whatever they forage.
I noticed that the 11 week old Uggos are now sampling the adult feeders off and on.
