I almost forgot, one of the things that irked me the most when I started was wasted feed. I went threw several feeders trying to get one that I liked for both space requirements and reduction of feed loss. I finally figured it out about 2 months in. Some birds will wipe their face back and forth in the feed causing it to fall on the ground and because my feeders were always full no one would eat the stuff on the ground. I salved the problem by placing chicken wire over the feed for a week. This stopped them from the habit and still allowed them access to food. After a week I removed the chicken wire and haven't had that problem again. Fermented Feed is also something that reduces feed loss and works great in the summer but can be a real pain in the winter because it has so much fluid in it that it freezes.
