Sorry I don't have any pictures but I have used free pallets (can pick them up lots of places- around here Sears always has them). I wire them together at the top (extra electric fence wire works fine) and then stand them around the pasture area in a teepee/a-frame formation (you can make them as low as you like- the grass holds them in place just fine). Birds can go in and out either end, they provide some shade, and sometimes the girls like to sit on top of them. So far so good. They are portable too. I've noticed that a pair of redtails is setting up housekeeping in the woodlot across the road so we'll see what happens this spring.
