I have dug a pond for my 2 ducks but I don't know what to put around it ? I have 2 options if neither of these sis suitable then they will have to be fine on mud as I can't afford to buy anything right now. First option , gravel that surrounds my house but I ca take some away and put it around the pond. May be to sharp though. I also have a big pile of stone that I can use, again may be to rough. Thanks your input is appreciated.
