I am building a new (although temporary) chicken coop this weekend in an existing shed. Because of the layout of our driveway, I will not be able to have an enclosed run until my new horse barn goes up this fall and my coop moves there. I would like to let my chickens go outside during the day when they are old enough. We do have coyotes in the area (we've heard them howling at night) so I want my chickens to come in at night. Here comes my stupid questions: Will they come in on their own? Is this something I have to teach them to do or do they know where "home" is? Thanks in advance.
