I have 12 chicks that are a little over 2 weeks old now, 6 RIR and 6 Buff O's. I am going to start building an outdoor run for them tomorrow which will be 12 x10 feet. I live in middle TN in the country and I know there are possums, coyotes, bobcats, and coons in my area. I had planned on letting the chickens free range once they are grown (I have several neighbors who do this successfully). Once I complete the run, then I will start on a coop for them to roost in at night. My question is this: is poultry wire strong enough to keep out predators? I plan on completely enclosing it (top and bottom), they wouldn't be able to dig under and get in, but could they possibly just rip through it? Thanks for any input on this subject...I don't want to have to build it twice!
