I used the schedule 30 PVC 90 degree 3" on my bucket above. I also used a 3" hole saw on the bucket. The hole was so tight that I had to use a file around the edges to open it just enough to force the elbow in. It fits super tight. I can't twist it or move it in any direction hardly, so I suspect my chicken's heads won't be able to budge it at all.
