That is pretty high tech!This is not a small waterer, but I love it and use it in my brooder. Mine is gravity fed as I don't have running water out there--but it can be connected to a garden hose as well.
I don't use it in pasture because anything elevated get's knocked down. I've given into rubber bowls (they can't break em) and kittie pools.
X2. I hope they don't mess with your birds...
