Would you buy this fencing? 4-ft high, as shown, with chicken wire. Can buy it all for $150. I'm pretty sure I will never be able to totally free-range my chickens (goal is 20 hens or so). Was hoping to have a big coop leading out to a completely enclosed fenced area...which I could then open into this fenced in area when I'm home and ONLY during the day. Can I have chickens in here or will that not work?
