This is more of a hypothetical question...since I do not plan on fencing in my birds with 3x3 wire fence. However I am getting about an acre and a half fenced in with 3x3 woven wire for goats and was wondering if down the road chickens could go in there. I would think that 3x3 could contain them but it definetly is big for poultry containment. Just wanted to hear others opinions on this.
