We have 60+/- in 4 yards, 3 pens and free range. We have been using the 5 gal plastic waterers, but as the flock has grown and the summer comes it will be hard to keep up. We had been looking into a design using the same nipples but a barrel reservoir that would need to be filled with a hose every couple days. This would be perfect . DH has already printed it out and is making notes to fit our structures.
Thanks for sharing
