I plan on making a run for the chickens I plan on getting next week, with a 6' chain link fence. I will be putting 28" high, mesh on the bottom of it to try and detour predators from getting in. Also I plan on making a wooden 'fence' on the outside of it as well. The run will be approximately 30x 15, so I'll have plenty of room for my, so far 12 chickens that I plan on getting Fri. My question is could I use regular bird netting for the 'roof' of the run? This is what I was thinking of :http://www.walmart.com/ip/Bird-Nett...r-Bird-Poultry-Avaiary-Game-Pens-New/29608046 . I'm not really sure if that will be good enough for hawks or not, but need something to keep them out!! Thank you in advance!!
