Quote: We dug an initial pond about 4' deep, about the size of a kiddie pool. However, the whole thing isn't 4' deep. We have a shelf in it for putting in rocks and plants later. The pond holds 1 large load of wash, with room for a tiny bit more water. So, we decided to dig a second pond for overflow. The second pond is slightly smaller than the primary (practically negligible). We're also planning to carve some shallow channels for water to flow to other trees/plants. All a work in progress. The ponds look like mud pits right now and when it seeps into the ground, the chickens love scratching and poking around. Local birds have come for water as well, and the chickens enjoy chasing them off THEIR property.
