So my flock puts themselves back in the coop at dusk every night... so cute. Their little door opens into a very secure run (made with cattle wire panels, hard wire cloth, bird netting over the top, etc) my question is: do I need to close their door at night or can I just let them be? They are VERY anxious to get out in the morning when I let them out. I am asking because we are going out of town for a few days and I have a girl coming over to check on them, but I don;t want them to be locked in the coop if she doesn't get over here right away.
