Hi:
I haven't set it up yet, but I'm planning to make my own version of the henspa waterer.
I bought a flat-backed bucket and a bucket water heater.
I didn't by the self-heated bucket.. I'm not sure how those are wired up and I don't want to ruin it by drilling holes in it.
I ordered some nipples from farmtek.
I haven't set it up yet, but I'll post when I do.
I'm not sure if I'm going to set it up on the inside or the outside of the coop. It seems to me that the nipples would be more accessible and easier to learn if they are on the inside, but then the bucket takes up more space, is harder to get to for refilling.
I can't find it now, but there is a fellow out there who built his own henspa-type movable coop with wheels, and he duplicated the henspa bucket as well, and has it mounted on the exterior of the coop. I wish I could find my link to the photos. He may even be on this forum somewhere.. I lose track of where I see these things.
I too have been surprised not to see more evidence of people doing this. I am all for a low-maintenance approach.
Suz.
