Haha, that's great! I'm thinking of making the bottom half of my chicken coop out of beer bottles like the glass houses you see on Google, this would fit right in.
Once I made it I was surprised how well it worked. I changed the beer bottle for a plastic coke bottle yesterday, the little red ridge of the coke bottle rests on the edge of the white bottom piece. this makes the water level a little higher.
Great idea to re-use bottles ♻. It gets better if you add a description how to make it. Is the white tub the bottom of a plastic bottle?
This way its not a real article.
If I want to install such waterer I have to make a bar first where the small tub can lean on and cut the hwc-wire.
