I am almost done with my coop ! My question is, do I have to actually lock the pullets up in the coop for a couple of days or if I just turn them loose in the run/coop( door open) will they know to go in at night? They range from 5 weeks to 9 weeks right now and there are 4 of them. This is exciting, I can't wait to get them into their new digs and out of the rabbit cage !!!!!
