I am just getting started raising chickens and only know what I have read. Attached is a picture of the chicken coop I just purchased to start out with, it says it is for 2 to 4 chickens. I do not have chickens yet. It looks pretty small to me, but if I was to get 4 chickens, what kind of waterer and feeder should I get? I was planning on getting small round hanging units but I'm afraid that they would take up too much room in this small coop. Any thoughts?
