Ok I have been reading posts and still not sure what to do. My 3 ducks are in the end section of my coop with a door that goes to what I guess was an old screened in room like my other coop but only the cement foundation is left. and dirt is down about 1-2' all ready. I plan on putting in a 300 g rubbermaid stock tank and rigging up some way to drain it some how and then filling in with sand and rock but which shoudl go on top. What size rock large or medium river rock or pea gravel and then a sand layer. I guess maybe I would do sand on top and ring the pond with pavers and rock. I am thinking too much help. Will add pictures if I ever remember to do it when the sun is out.
