I put my Chix' food in plain old heavy-duty dog bowls. I only have 2 chickens (should be 3 and will be again), and I never leave food out at night in order not to draw predators, so I don't use those big hoppers. This works pretty well, but esp w/ their a.m. oatmeal (layer pellets, rolled oats, ground flax, eggs, cooked in m-wave and allowed to cool) they sometimes, in their excitement, drop big chunks outside the bowl. So I'm now putting the bowls on concrete pavers. I figure this will not only make it easier to pick up spilled food, but if they peck at what they do spill, it will trim their beaks! We'll see how it works!
