I am so glad I found this posting. I'm sure I thought something was wrong with my chickens. They've been out in their new home for two days in the mornings. We open up the Coop run and they've started to come out and enjoy themselves. But when it gets dark they won't go back in the in they just huddle in the corner of the chicken yard and we have to gather them all up Stick them through the run door. I would assume that they will eventually get it and go back in at night. I am not at all thrilled that I might have to take my chickens in at night forever. So I will turn the red light on the heat lamp just at dusk and come back and see if they went in, It is my hope that they will get it. THE MORE SUGGESTIONS ON THE SUBJECT WOULD BE HELPFUL
