Well, how handy are you?
I have to do some of the projects too, because my hubby thinks they are neverending....partly true
. If you can afford it,I thought about building one with wooden privacy type fence panels. dig 4 post holes. attach 3 panels, put a cyclone fence gate or one you make out of kennel fence 2X4 or 2X2. And /or make a wooden door frame and attach the fence to it. The front would be just fence and a gate. Roof could be plywood,, fiberglass panels, etc.
Or cheaper, just buy a roll of dog kennel fence and put 4 posts, wood or T and attach wire all way around including top . and put a tarp on it.Or outdoor fabric like they make awnings out of, (often on clearance at fabric stores). You will need to put hardware cloth or wood on the sides ,up to 2-3 feet to keep raccoons from grabbing thru wire ,if they are in your area. I lost geese and chickens years ago to them, not knowing how smart, determined and l prolific they were in my edge of the suburbs area. .
Some people find plastic playhouses or wooden ones or dog houses and convert them. You need wire and a tough tight night door, or eaten ducks......----Hotwire around and top and bottom of night pen or house keeps most everything out.....
