OK, I've had a new run constructed to keep the hens out of the main part of the garden so they don't eat it all! It also keeps the dogs from harrassing them too much. Inside this run I've positioned the Eglus, which I like to leave open during the day so the hens can stretch their wings a bit. Here's a photo of the run. Now, there is still finishing to do. I will add 1/2 inch hardware cloth along the bottom half and put pavers along the outide to deter digging. (I have lots of extra concrete pavers from another project.) My big issue is what to put on top of the run to secure it from things climbing and flying inside. Since I do lock the Eglu runs closed at night, I guess I'm not too worried about racoons and such attacking; the hens and chicks go into their coop at night and are not inclined to come out at all. So, I doubt that a night-time predator could get to them. However, over the past month or so the sparrows have discovered my hens' food. These flying pests eat a lot of the crumbles and I'm tired of giving them a free meal. So, how do I keep the sparrows out? If I just get some bird or deer netting and secure it over the top will that work? How do I secure those long segments so they don't fall inside the run? The dimensions of the run are sort of odd, as it followed my odd lot lines. It's roughly 20 feet long by 12 feet wide at the widest point. I was originally going to try to cover the run with a SunTuf roof but after much discussion here with others it just didn't seem feasible without adding all sorts of extra posts inside the run. Snow load could be a real problem without extra support. If there is a way for me to add something to really secure the run from predators climbing in, then I could take the runs off the Eglus which would make walking around in there less awkward. Thanks in advance for all your ideas!
