I saw a cool way to make a feeder. I wish I could show you a picture. But Ill attempt to describe. I got to go to work so only have a few minutes.
1. get a 4" diameter ABS Pipe. Its Black in color. 6 feet long should be fine, but the store will probably only sell a 10 foot piece.
2. Get a 4" Abs 45 degree bend.
3. ABS Glue, but that is probably optional
Okay cut that pipe in whatever length you need. I think 2 3 foot sections is good.
Now put one pipe into one end of the 45 bend and the other pipe into the other end of the 45.
It should look like this ,
You put feed through the top, drill holes through the bottom pipe. Hang on the wall using ABS 2 Hole straps < 4" ones of course. Or you can just use plumbers metal tape. But the two hole straps are better.
I cant help out with a waterer at the moment. Ill have to think about that
