Their mother hen already shooed them away, and it's been really hot so I haven't worried about the temperatures. But tonight it's raining and supposed to be low 60s, and when I shut their dog crate nursery up, I noticed they were peeping in the back of the crate, all trying to crawl under each other. Was it because of temperature, general nervousness without a mother hen, or the rain making them nervous? 90 degree day, 62 degree night. Is that too cool for 5 week old Dominiques?
