We're very limited to the types of food available around here. No game bird feeds of any kind and all the poultry/turkey crumbles are medicated. Turkey grower pellets are available (22% protein) but they are too large for my birds to eat. I've tried making the pellets smaller by grinding them in a coffee mill and a food processor but end up with mostly powder which the birds won't eat. We can get poultry layer crumbles but they are only 17% protein. My question is: what can be added to the layer crumbles to bring the protein levels up. I know you can add all kinds of things to their diet (mealworms, etc) but I'm looking for something that can be premixed into their food. Something that can also be adjusted for various protein percentages as we have a few different types of quails with different requirements. Would it be possible to add something like fishmeal or sunflower seeds to make the protein levels correct?
