My 4 hens have a netted run, approx. 225 square feet. They also have a much larger fenced area which they get to roam when we are at home. One of the girls insists upon flying over the 40" plastic fence into the garden area. I can tell from the way she acts that she knows I am not happy with this. After I herd her back into the fenced area if I am able to catch her, which is not too often, as I said she knows, I place her in a small enclosure for 15 or 20 minutes. I have only recently started doing this. Will she eventually make the connection & cease this unwanted behavior or am I wasting my time? Thanks!
