That is a great job. Not only are your systems for feeding, watering and egg collecting great, but your coop looks very safe, which for me, is the most important. It certainly seems like you have taken all the best ideas from this site and applied them beautifly to your coop. Once again...GREAT. Now make your run with the same care for design and safety and we will never be hearing from you in the Predator section.
I saved the link to your page in my collection of ideas for my coop. My coop is almost done with the main construction but I have yet to set up feeding and watering systems, etc.
Am going to borrow your feeder idea. I also made one out of PVC, but I drilled holes om the horizontal pipe for them to eat from, but the feed was getting stuck & not flowing properly.
