Hello, reading the posts about predator protection, my two neighbors might have some good ideas. We have coyotes, foxes, coons and maybe even ferrets to contend with. These may seem drastic and judgement needs to be used as to the "corridor" width you'll need and used in areas where your chickens (or other pets) aren't roaming about. One neighbor uses a 4-foot-wide corridor of broken glass, large, sharp chunks, around her run - obviously the outer portions where she -- or the chickens - do not need access. She swears by this and I can see why it would work. She has 38 or so chickens and hasn't lost one to a predator in years. She admits this may be harsh on the neighborhood cats.... Another neighbor's solution is similar but perhaps not as drastic. She combs yard sales, Goodwill, Salvation Army for metal forks. Then she pushes the handles into the dirt, leaving the tines sticking straight up, spaced about 1" apart. Her forest of forks is about 2 feet wide. Looks odd, but who cares? This works well for her garden, too.
