No, not navy beans, I use the 'small white beans' exclusively (I actually think they are the same variety as Navy or Northern but just smaller but I am not sure). This is because I will only use white beans and I have different species of birds, some small, some medium and some big so the small beans 'fit' everybirdy
I am now using kamut, oat groats, hulled barley, black and/or red rice as well as wild rice, spelt and/or freekeh and black lentils (all cooked by me in batches of stuff that cooks in the same amount of time: oats with barley; rices with lentils; and the rest, which are all 'wheat like' grains together) to this I add canned small white beans which I rinse very thoroughly under running warm water as well as the following frozen veggies: chopped broccoli, peas and carrots, corn, butternut squash and chopped artichoke hearts. Lastly, I add the baked sweet potatoes (or yams) which I nuke in a Potato Express bag during the warm weather months and bake in the oven during the cold ones (I don't turn on my oven when it's warm), flax and sesame seed. I use more or less the same amount of each grain as I do of black lentils but much less white bean, flax and sesame seed and add enough veggies so it ends up been 50% veggies and 50% of the higher protein foods (grains and beans). I make a huge batch of grains/rices which I split into two, one half is prepared with veggies and the other is frozen for later. I buy in bulk and use about 3/4 lbs of each grain but buy the rices in the usual package sizes so the wild rice ends up been less than the other rices. I then add 4 cans of beans, 4 packages of broccoli, 1 large of each peas/carrots, corn and butternut squash (it comes cut up into little cubes and frozen), a smaller one of artichokes and a good, generous sprinkling of sesame and flax seeds. When I want to increase protein (during the breeding season all the way to molt), I add quinoa to the mix and, sometimes once, sometimes twice a week, I add a bit of freeze-fried mealworms to their daily gloop.
Now, you can use whole wheat kernels, either hard red winter or soft spring white wheat instead of the 'wheat like' grains I use. I used to but decided to switch to the 'ancient' grains instead because I believe are closer to what nature intended grains to be and not so high in gluten.
The easiest gloop is to buy Kashi's 7 Whole Grains Pilaf and simply follow the directions on the box (you can cook them in the microwave) and add veggies to it, but my birds are not partial to rye -which this mix has- and, as I do these large batches, I prefer to buy the stuff separately. And, its really not hard at all for me because I can actually get everything from my supermarket 'health food' section (next to the organic section) with the exception of the black lentils which I have to get from Whole Foods. Years ago, when you couldn't find whole grains in bulk anywhere, I used to order them from here:
