I am wanting to let my chickens free range in our backyard. We live in town. We have a 6' privacy fence. I don't want them flying over the fence into neighbors' yards as most of them have several dogs each. One immediate neighbor has 4 large breed dogs that run loose in their yard most of the day. I have a dozen pullets and will have 2 roosters I am going to keep and 4 more that are going to be raised for us to eat. I also have some ducks that are running free right now. I am thinking of clipping their flight feathers. Didn't want to do anything as permanent as pinioning. I would have to make several smaller or one bulky Chicken Tractor if I don't clip their flight feathers. What is the consensus on wing clipping?
