OK, so I have my first chickies. Eight little birdies. They're now 25 days old. I have the plastic bottle feeders and waterers. White bottle, red bottom. The chickies are in a cardboard box. They either throw all their pine shavings in their food/water, or knock it over, or both. I tried putting the water on top of a inverted pan, but they knocked it over. I tried putting it on top of an inverted pot dish, but they knocked it over and threw shavings in it. Is there any good way to keep them from knocking over their water and/or knocking shavings in them?
