I found that boiling eggs after they freeze are ok to eat . the birds will scatter the corn and pellets looking for a perfect size,lots of waste I spread the food out thin in different containers so they can see the bottom. They won’t waste any i’ve tried 20 feeders, and made five,rubber cattle bowls work best for my ss I run 2 extension cords for heated water until I can rig up solar hope that helps enjoy👍
