Angela, could you post a pic of the concrete soaker that you made, the one being used by the ravens now? I might try making something like that. BUT, in the summer mold builds up in the water and with the rough surface isn't it a problem?
My father once built an outdoor laundry sink/tub by making a mold in the ground and then pouring concrete on it. Then he lifted the thing and righted it and voila, he had a sink.
