We are in the process of moving to a more rural area. Right now our two chickens free range in the day time and have been totally safe in our suburban back yard. Our new home has tall trees on the west side, and an open area along the north. The perimeter of our new yard is fenced. We are mostly wondering about birds of prey and trying to make it more difficult for them. Any ideas? We want to keep free ranging our chickens. We have 2 dogs that will help watch over the chickens in the daytime, too. Do areas for the chickens to take cover help (like bushes)? Would it be best to locate the coop and run (completely fenced even on top) under the tall trees on the west or more out in the open towards the north? Thanks!
