at 11 weeks or so i able get my birds to go in at night. at first (at 8 weeks) i was putting them in at night on by one then i heard that putting a small light on at dusk will get them in......and it works, had the light go on for 3 nights at dusk , yesterday i shut the light off completely and at dusk they went in with out the light. mission accomplished. now i shut the door every night cuz of the critters. thanks for the light tip.
