Hi all I found this design for a simple chicken feeder and as I already have made a different one https://www.backyardchickens.com/t/843581/my-bird-and-rodent-proof-feeder and don't need to make a new one I thought I would share this find and if anyone tries it maybe they can post back to see how they go. As the designer says start with a smaller hole depending on what you feed because you can always make a smaller hole larger but it is more difficult to make a larger hole smaller.
