Very new here...I have 8 six-week old chicks (pretty sure 7 females and a roo). They have been in their coop (an 8x10 wing of our barn) for about 3 weeks, with supplemental heat dropping each week (now on no heat). It's finally nice enough (and their 8x16 fully enclosed pen is finished)....but they won't go out! I started with opening the door and trying to lure out with treats, but they wouldn't go. This morning I moved all 8 out, one by one, and within 5 minutes they were all back inside. I have moved their feeder out hoping to coax them out, but don't want to stress them too much or withhold feed. Do I move them out but block access back into the coop? Any ideas or suggestions? Thanks!
