I need help. While I was in the process of building the run, I allowed my 2 month chickens outside for short periods of time. In that time, one of them figured out how to perch on the fence. At the time it was 4 feet high. I have since added 2 feet on top and tied the two layers together, and she still manages to get on top of it. She's escaped once by jumping off the other side, but i don't think its her intention to escape, just to perch. I'm also concerned because "her" fence is right along my neighbor's yard, and my neighbors have dogs. What should I do to discourage this? I want to avoid putting a roof on the run but i don't know what else to do.
