I have a huge space sectioned off by chain link fence within my property. I want to either add on to that, or replace the chain link with whatever is needed. But basically it need to be raised up higher to about 10-20 feet, and enclosed, with a large swing door on the outside. and a section closed off from the large door for double protection (so two large entrances ) . The width is probably going to be about 10-20 feet , and the length is real long . Maybe hundreds of feet . So basically like a long rectangle. I still need to do measurements. This is only to let my birds free fly, in an enclosure for fun , exercise and for training purposes. I want it to be very basic , sorta like what you see with a out door dog kennel, but obviously with smaller spacing holes in the wire, than with a chain link fence. I canot afford to do it now. But would like to know where to go to begin planning my purchasing of supplies for it. Do I just go to lowes ? or home depo?
