I want something that I can be ensured my dogs do not get to my chickens! I have two olandsk dwarfs, and I want something I can move around the yard for them to graze but safe from my dogs. I found this http://www.frugah.com/78-Deluxe-Wooden-Chicken-Coop-p/d3-0017.htm?CartID=1, and they have other ones. What do you guys think? Has anyone purchased similar coops or any coops from frugah? What do we think regarding their construction? Strong enough to keep my precious babes safe?
