So I went out to the coop this AM to check on the ladies, and my little leghorn is hiding in the corner. She's usually shy anyways, but when I come in with scratch, they all usually get a bit closer to me. Her feathers were really fluffed, and she looked like she was trying to stay warm--head buried in the flocked feathers, etc. It was fairly chilly last night (probably got down to 40 degrees or so), and I'm thinking that maybe that's what's wrong? But wondering if there's anything else I should be looking for? This is my first flock of chickens. I have 6 of them, and they're all about 11 weeks old now. One rooster, and 5 pullets. Any ideas, or what to look for will be helpful!
