Have been using my Totally Waste Free Funnel Bucket Feeder for about a month now and am now convinced that IS waste free. Updated 12-4-14 to say Totally because it is proving to just that! I liked the trigger feeder concept seen around for a couple years from the UK and feel I improved it's use by installing it in the bottom of a funnel so all the feed in the container could be distributed. I wanted a 'deep dish' feed pan to minimize any billing/beaking out of feed onto floor/ground. I thought about this for months before finally putting it together, it went together so easily and is easily modified if needed. I did make a couple changes to the trigger aspect but now thing I've got it just where I want it. Underlined text above, in first sentence of the post, will take you to all the parts and details of construction and installation.
