We used to let the chickens free range all day because my dog would watch them. Well since we got chicks, she was to either play with them or eat them, so we can not let them out at the same time. Well we went to a friends in between morning church and night church so I got home at 7:30 and figured I'd let the girls out for a couple of hours. I put the dogs up and let them out. They were out for 5 minutes and then put themselves to bed! I opened the coop door and watched as they found their places. It was funny to watch. The chicks would get in the prime spots just to be knocked down to a lower place. I can imagine this happening every night.
