I'm making large runs with t post and welded wire. The coop is going to be a 2x4 frame like a shed with exterior plywood walls. Below is what I'd like to do, red box is coop, blue line is fence, green line is gate on it's pivot point. Could I attach a pre-made chain link gate or maybe make a simple gate out of 2x4's and fencing? Preferably it would be something I could attach right into the existing structure without putting in extra posts.
