Specially interested in chickens
The previous poster is right, they are too young. Try putting some scratch grain (favorite treat) or feed in the coop at dusk and CALMLY herd them in to the coop. Don't chase them, they will never learn when they are scared. Putting an owl decoy up will terrify the chickens.
The only time I have ever had to get up during the night because I heard the chickens upset about something and it turned out there was an owl on the clothesline which is right in front of the coop.
