I had a difficult time getting the chicks back in their coop last night to shut the door... it was their first night outside. I won't be closing the door for long though when it gets warm enough to leave it open all night. But once I start leaving it open, will they start going in on their own to roost? Last night, even if I was going to leave the door open, I don't think they would have gone in on their own. They were just all hunkered down together sleeping in the corner of the run away from the coop. I had to lure them inside. If I would have left them out, they would have gotten cold and soaked from the rain. I guess my question is... do they have enough sense to get in out of the rain and cold? And how long does it take before they get into the habit of going in at night on their own? These girls are 5 weeks old.
