Well, I spent the day outside surveying the property around my barn. I came up with the maximum available measurements for my chickens' run area: I have 20' x 16', with the 8' x 4' shed coop placed inside. My chickens will also have my 1/2 acre pasture to roam during the day - the run is only meant to contain them at night, and when I'm on vacation, so my relatives don't have to chase down chickens for me. I'd also use it extensively in the winter, so that they'd have a semi-protected place to hang out. I just don't know how to fence and predator-proof such a large run. Ideally, what I'd like to see is: A tall fence that will allow me to stand inside A covered top of some kind (even just hardware cloth on top would be fine) Able to handle snow loads this coming winter, with some modifications Not permanent, since eventually the run will be incorporated into the horses' dry lot/paddock - I'd like to avoid digging post holes if possible Looks neat and tidy The footing will be 4" of pea gravel for drainage and cleanliness. Any suggestions and especially pics would be great!
