Hi All! We've had chickens before but have been on a break for the last 5 years. They've almost always been kept in a coop with no issues, but I'd like to give our next flock the run of the property. Our yard is about 200' by 100' with cow pasture on two sides and a fairly busy road on one side. I'm hoping you can give me advice on whether or not we need fencing all around? and if so, how high and sturdy it needs to be? The chickens will be back in the coop for night time and the yard is mostly treed; stray dogs are not an issue. We have a few neighbours who don't fence their chickens and they don't go near the road or out in the cow pasture and one who just uses 3' high snow fence but that seems a little risky to me. thanks for your help!
