I learned a lot from this thread. From the beginning when I started my colonies (dubia and red runners) I was going by the information I had found regarding keeping their protein percent low to avoid uric acid issues. I have always mainly fed oats, grains, and supplements like bee pollen, but have had wing nips in my Dubia colony. I may try a higher protein diet with their usual vegetable offerings and grains included and see how they react.
