Now being there shiny that might work. what your going to have to do is get the whole thing the way you like it then stake it out and see what happens while your ducks are out in there. That maybe spaced okay best thing to do now is try it out, do you have a place close by like a window where you can watch without being detected so you can see what goes on. That is such a nice space you have for your ducks, I can see one of your ponys too.I could also put the cd's on top of the posts and attach them so hopefully they will be to scared to land. What do you think about the spacing?
