I'm interested in getting 3 or 4 chickens that I would keep in a coop with an enclosed run and would like them to be able to roam the yard a couple hours a day. The biggest thing holding me back is I'm concerned that our fence isn't high enough (3.5 feet) and seeing as how we are in the middle of suburbia and surrounded by neighbors on all sides make shift extending the fence isn't an option. I'd hate to be that neighbor who's chickens are in everyone else's yards or worse the neighbor whose chickens got eaten by a dog when in some one else's yard. The breeds I'm interested in are on the heavier side (7-8 lbs) which I've heard can't jump as high but 3.5 feet seems like a short hop for a determined chicken, even a heavy one. Thoughts, suggestions? Thanks!
