Is it necessary to cover the chicken run? Our original plan is to do a "chicken moat" style run around the garden. The plans that we saw for this on Mother Earth News' website, shows most of the run open. My good friend has a nice big run at her farm that isn't covered and has never had a problem. We plan on shutting the chickens in the coop at dark. What are the pros and cons of having a covered vs. open run? We do have a few coyotes in the area, but we also have a black lab and some nature lovin' home schooled kids that are playing outside all day, so we have a lot of activity going on in the backyard in general. We purchased 6' tall fencing and we only have heavy breed birds.
