I have to agree that paint cans make a good feeder. I just go to home depot and buy the new unused cans. A couple of small holes in the lid and you have it. Of course I find that just about any pail, jar, or can that has the ability to seal works well. The bigger the better. If I can recycle it all the better. I sell some commercially made feeders but not to many as I try and teach people how to use what they have to make their own pail type feeder instead. Just make more sense and I think they are better.
