I've only had these little peepers since Wednesday. Maybe this is not the best type of feeder that I am using? I have it set up on a piece of 2x6 to try and get it up around the height of their backs. They still fling an amazing amount of crumbles out on the ground. Should I let the feeder run out and make them eat crumbles off the pen floor? It's not like there's only powder left, there's plenty of big chunks left. Any ideas on how to get more food into the chicks and less on the floor?
