It's my girls (7 weeks old) third or fourth night out in the coop. They put themselves to bed which was awesome but when I went to take their food up and make sure all the doors were locked they were shrieking like mad. I peeked in through the top vent and then were climbing all over each other in the corner by the door. I know it's really hot in places but I'm in the Bay Area in California and it's going to go down to 50 tonight. Are they cold? Should I take them back in? They weren't just huddled together, they were climbing on top of each other and I'm worried they will smother someone. Thanks!
