Well, I couldn't stand the thought of them never getting out of their pen to eat grass and bugs again. So, while it doesn't look quite as nice, I fenced off my flower beds and vegetable garden from them. It doesn't take much to discourage them, so I got some cheap chicken wire that is about three feet tall and put it around the area with some re-bar pieces as the posts threaded through the chickenwire about every 6 feet or so. It doesn't sound too pretty, but truly, from about 10 feet away you can hardly see it, and definitely not from the road or driveway.
Now the vegetable garden needs big protection too, so we put a T-post in each corner and one more along the long way, then got some deer/bird netting for something like $10 at Lowe's and used zip ties to attach it to the t-posts. The 100 foot length was just enough to go around. We wrapped the end of it around a stake and use that at the corner as our 'door' that we hold in place with other loose zip tie that we slip down over the Tpost and the stake to hold it up in place.
Once the chickens know they can't get in those areas, they pretty much stay out of the area. They do check, however, because once I left the 'door' to the garden open to go do something and those little peckers got in there behind my back!! Good thing I love those darn girls so much!!
