Okay, I should say I *am doing* it. I am in the process of making one of those no-mess, no-waste 5-gallon bucket feeders. Thanks to all who posted instructions and pics, this looked so cool and practical I had to try it! I used Gorrilla Glue (r) to get the PVC elbows set in place, and when the glue is dry (Sunday, because tomorrow is Sabbath), I will caulk them in place. Can't wait to try it and see if the hens use it! I hope the bright, screaming Home Depot orange doesn't scare them off!
The empty water bottles are holding everything tight and snug till the glue dries....
Oh, and if you make one of these, be sure and DON'T get the elbow with the big fat flange on both ends!
