Hi all: I currently have 4 hens free-ranging in the back half of my 1-acre lot. I've recently tilled up a small plot for my wife to do some vegetable gardening. I'd like to put up some fencing to keep the hens out. I realize they can probably fly over whatever fencing I do put up, but I'm wondering if they have enough room in the rest of the yard to not want to bother flying into the garden area. If a mesh fence (pig fencing, maybe?) will work, what height should I go with? Thanks in advance!
