My chickens are 8 weeks old in they have been out in their coop and run for a week now. Today it is absolutely pouring out. First time they have experienced rain. My run has a metal roof over it. I have a waste paper basket layed on its side with shavings in it, because I'm not sure they will go in their coop, even if they are cold or raining. Still won't go up ramp on their own. I just went to check on them and they are all in the waste paper basket. Should I put them in the coop seeing it is raw and raining out? Thank you Kim
