I also use an organic mash feed that is quite powdery. My solution to it, since I don't want to switch feed (it's soy-free, non-GMO, organic) is to keep a little in dry form in their hanging feeder and to mix some with warm water every morning and offer it in a pan. It took a bit to figure out how much to make, but they eat most of it up in late morning, early afternoon, and then when it starts to dry out, I toss the remainder (less than a handful) on the ground, and they scratch for it
