Hey everyone. So i have 3 silver laced hens. They are 8 weeks old. I have had them outside since earlier this week. But it is supposed to get down in the high 30's the next few nights. I was wondering if i need to bring them in or if they are okay to stay out. There coop is tightly sealed so there is no draft. I also have straw in there. And at night they usally sleep togeather in a nest box with straw in it.
