Blocks under the feeder helps until they are big enough to knock it over or perch on top. I use one like yours but with a glass jar so it is much heavier. I still think it could be improved and I intend to build a wall-hugging hopper with a long, narrow hole so the stinkers cannot poop in it or scratch it out and they sure as heck won't tip it over. Next time.
For water, I use the poultry nipples; no spilling, no fouling, no wet chicks, no drowning. After trying those, I'll never go back to an open dish of any sort.
