How big of a "yard" do standard breed chickens need? I have 5 little ones. The house is on the smaller side, 15 sq ft. I want to give them plenty of room to be happy! How deep should the fence be burried? I live in a small city, I think the biggest threats come from a possible racoon or opossom. Should the feeder and waterer be kept inside or can it go in the outside run? Does it matter? (obviously I will need to keep the water from freezing either way in the winter) Do the food and water need to be both kept in the same place relatively? Thanks so much!
