We trained our chickens to go up to the coop on the first day by showing them how to walk up the steps. They got a hang of it after a couple of nights. This is the ritual they go through every evening.
On a technical note, it was getting dim, so I cranked up the ISO to 800, set the shutter speed at 1/50 in a shutter priority mode. It turned out like it was taken at daylight!
