We attached them to a bucket for a friend of ours, but here are the pics of the waterer we fashioned with PVC. We used a feeder bucket to supply the water to the PVC waterer. We will have a splitter to supply two lines from the bucket when we set up our second brooder. This will go out to the coop when they get big enough to move out.I'd love to see a photo of them attached to buckets; I've not had any experience with those but have been curious about them.
