Hi folks I installed a couple of PVC feeders in my coop for my young chicks, and discovered that even when hung up high the chicks managed to spill lots of feed out, so I cut out a couple of feeder "collars" using a rubber type material similar to the silicone baking sheets you can purchase cheaply from Walmart. Put a few pecking holes in and you are set. The spillage is now minimized. I have enclosed a few photos. Since I got the idea for the PVC feeder from BYC, I am "paying it forward" - maybe someone will find this useful.
