I have a portable solution for my ducks...I have a 24 foot length of 36" tall hardware cloth that I use as a potable duck yard, I move it to a new area every day and the ducks and geese eat all the weeds. I just put some water and a bowl of feed in there, every other day i give them a masonry mixing basin (home depot for $6.00) full of water to play in. To stake it in place I use some 4' long pieces of rebar, so my enclosure is like a 4x8 rectangle... I generally put a board across the top near one end and drape an old rug over it and a side of the hardware cloth to create some shade too-which my dark brown hybrid ducks really appreciate. this whole thing take 5 minutes or less and works really well... and it can be rolled up when not in use.
