Hi, I introduced a new pullet (about 10 weeks old) to my flock of two pullets (13 weeks and 9 weeks old), and although there's no fighting or squabbling, she won't come out of the coop. There is no water or food in the coop--during the summer both are affixed to the run. It's supposed to be 95 degrees and hazy humid today, I had to go to work so I can't stay home and work with her. Will she die, or will she eventually come out looking for sustenance? I'm new to chickens, and not sure how "dumb" they can be about these things. I'm so worried! My other two girls stay together at all times and are acting normally.
