Catch system to collect the food that was spilling out of t he feeder. Smart way to not waste food and prevent the all-you-can-eat mouse buffet. - build a box about 1 and inches deep and laid the plastic grid from a florescent light in the top.
Chicken feeder- Consider a wooden box with turned up opening at the bottom (similar "J" principle) that accepts a full bag of chicken feed. A lot less tedious than filling each individual tube. It's less expensive too.
