That's a really neat hopper! Looks a bit too hard for me to make on my patio though lolol
For sure, it would be to hard on my patio also. We are having them made by a metal vendor.
Just showing everyone what we came up with to solve a feeding problem and maybe this will help someone else. Wanted to make something that would hold the food inside the tub and also be low enough to the bottom of the tub so that the babies could eat from it when they are ready.
