I just got my nest boxes in the coop yesterday. My BOs are about 22 weeks and have not started laying. I'm wondering if I'm in trouble since I didn't have boxes in at 18 weeks as recommended. My girls free range in the vegetable garden, and don't seem to ever go into the coop during the day--that's where my nest boxes are. Will they just figure it out on their own? My coop is not very big so I don't want to lock them in it during the day, also there's ventilation but not any windows so it would seem mean. Advice please!
