I recently acquired 8 birds (mostly Rhode Island Reds) from a friend, and built a 12x8 outdoor run attached to my old barn. The ground was pretty soft b/c i graded it smooth with the tractor. I strung chicken wire around the run, but within a day, the birds had dug a 6-8" trench around the fence, presumably while scratching for bugs/weeds. I filled the trench back in but they dug it out again! I'm worried they are going to dig a hole they through which they can escape, and my dog is a confirmed chicken-killer so I don't want a bloodbath in the backyard. Does anyone else have birds that dig like this? I had no idea they dig this much. Any suggestions on preventing an escape? Seems like if i bury the fence they'll just dig down enough to get under it. Thanks!
