My 16 chickens are ages 4-18 months old. I have always kept them in a coop and run due to neighborhood dogs. The neighbors got rid of the dogs and I really want to let my chickens free range on days I am off from work. So I have two questions. How far will they roam and will they go back to the coop at night? Between our land and family's land we are on 7 acres although I'm sure the chickens won't respect the property lines. Sorry...one more question. Our two dogs (who would definitely love a chicken dinner) live in a 3000 sq ft fenced area. The chickens won't try to fly into it will they? The fence is only 4 ft tall. Thanks in advance for any answers and advice.
