I’m building a new home. It will have an attached garage. I have an idea to make an egg box built into the wall of the garage (kind of like a dog Door . My plan is just to have 3-5 chickens in a shed just outside the garage, and the egg box will be in the wall of the garage. My contractor is concerned about the smell of the chickens getting into the garage and house - what do you all think? Anyone have experience with chickens and garages?
