Wow, those are really cool. Is there anyway you can take more pictures or even measurements and send them to me via pm?
Apart from the brooders in the basement, we also have some outside, as well as grow out pens.
They all have water and electricity :-
with automatic waterers inside, plus a wire bottom so there's little cleaning;we move the birds to a clean pen, then move the other pen to a new spot.
When the birds don't need heat, they can go to the grow-out pens - when the tops are removed there are hinged wire doors so the birds can enjoy the sunshine without escaping!.
All the automatic waterers are on a pipe base so spilled water (from the ducks) is removed via a hose running down the hill.
We have chickens and ducks so they had to be dual purpose.
