We started putting metal on the new peafowl home this past weekend,,got the roof almost done and will add metal to the sides this weekend then the building should be completed.But I'm always thinking ahead and the pens will be the next challenge.I've considered using chain link fence 100%,,(for the pens) or possibly laying a piece of metal siding longways so it's 3' high width will be all along the ground so they cannot see into the next pen Chain link fence is expensive and hard to work with alone.I've considered using 2"x4" welded wire on top of the 3' metal siding,,the 2"x4" welded wire comes in 48" and 60" high rolls,and if I use the 60" high this with the sheet metal base should get the pens 8 feet high.Is it better to have the pens so birds cannot easily see into whats going on next to them? I can skip this part and it would make building pens a lot faster.Or I can use cattle panels,,they are very heavy wire,come in 16' lengths and are 50" high,,these can go on top of the sheet metal side walls instead of the 2"x4" welded wire.Or I can build each pen completely with these heavy wire panels. But my biggest obstacle is the netting for the top.I do plan to use 2x2 diamond shaped netting with the highest strength they make,125lbs breaking strength.But what has me wondering is,,how to do this.The pens will be 10' wide and 32' long.wood 4"x4" posts will be placed every 8' along the perimeter and the inside pens dividing walls as well.I don't want to use wood across the tops of these wood posts to hold the netting up,1) They will eventually sag 2)they get expensive especially if using treated wood 3) Any rough spots can snag the netting causing it to rip. I've looked at using PCV plastic pipe to lay the netting over,,then using 1/8" stainless steel wire rope(cable) to pull this framework up to 8' high then building the inside pen walls.1 1/2" PCV pipe seems very strong and is only about $4.50 for a 10" piece,,I've considered using just the 1/8" stainless steel rope only as the framework to hold the netting up with.With spans of only 8 and 10 feet on the 4"x4" poles,,I think I can easily pull this cable tight enough so it won't sag,and the breaking strength is 1725 lbs.on this size steel rope-cable. Is it easier to install the netting before building the interior pen walls,or doing everything on ladders after the pens are built? How hard is it to pull and attach the netting so it's tight enough by yourself?
