Here is one of my summer projects. It is "Ducky Dome v2.0" (DD2). The thicker PVC proved too rigid for me to bend all the way into an arc like DD1, so I had to put some angle pieces in so it actually is not a dome any more, but the name stuck. It is built on the same 15' x 30' base DD1 was.
There are several improvements over DD1.
*4 supports instead of 3.
*10 Steel wires run the entire length on the top pieces so that the tarp can not fall into the dome if it should tear free (that is what took out the first one).
*Put 2x4s along 30' side to try to battle warping in lumber (partially successful).
*Tarp Anchor strips are now structural 2x4's instead of just being held on the pvc.
*Because of the above, dome is now supported internally from front to back so it no longer needs external guy ropes.
*Clamps were fitted to the tops of the supports where they meet the PVC so there are no edges to wear on the tarp.
*Little yellow crocodile holds the entire structure in place.
Note the tarp anchor strip you see is crooked because the street side one is perfectly straight. The side away from the street was positioned to get a constant tension on the tarp and reflects all the imperfections in the pvc and the base support structure, so this is actually by design.
Ducks' favorite place in the world is lying under the bottom beams.

By the way, all of you out there who have a little ramp going into a house that your ducks are balking at. Look at the ramp going into this pool. 15 out of 15 ducks can navigate that ramp and none of them has fallen off of it more than once (when they were first learning). Your ducks are lying to you and trying to make you believe that going into the house is too hard because they want to stay out and play with the predators (no one ever accused ducks of having good survival instincts). The difference is my ducks WANT to go into the pool, then after a while they WANT to come out and eat. Oh and guess where their favorite preening spot is...
