hello, we have 5 hens. 1 is from our old flock and four of them we got new about 2-3 weeks ago. All are about 14 weeks old. They will not come out of the coop. They scratch around in there. And roost. All day. We open the door every morning and the only time they have been out was when we brought them out. Our original hen was one of nine and the old flock came out as soon as we opened the door. What are we doing wrong here?? A pic of the coop before new run and new ramp.
