This is not an advertisement for this product I saw an ad for this feeder on Craigslist, and I was wondering if anyone has ever tried this? I have seen other trigger type feeders, but not one like this. I am pretty interested, as it seems like you could keep your food waste down, and give the birds something to do at the same time. Right now we are using bowls, and it is such a waste. I have tried the hanging feeders, and they seem to pull about half of the feed out of those, too. Thank you for any input!! http://www.peckomatic.com/ Here is a link to the website, and there is a video of ducks using the product.
