I get an occasional email asking if their chickens are too stupid to use our feeder and have learned to ask for pictures before answering. As one or two commenters already pointed out having other sources of water or food while trying to train birds to use a preferred method is usually the problem. The problem isn't that the chickens are stupid.... and I better stop right there.
First thing I would do before you give up on a particular style of waterer/feeder is to first go back and re read the directions and see if you are following the the instructions. People naturally fall into two groups; those that read the instructions and those that toss them in the trash. Fact is that the manufacturer wants you to succeed and has usually put a lot of time and attention to writing the instructions. They have dealth with thousands of customers, you have never dealt with their product in most cases. Who do you think is going to know best?
