Up until a week ago the chickens had a driftwood stick, about 1" wide to roost on. They loved it and I loved to see all 13 of them lined up roosting. It managed to get cracked, so I replaced it with a 2X4, flat side up. Now they will not go on it. One or two hop over/across, but they will not roost on it at night. It is cold here, about -20*C (-4*F), so I would like to see them using the roost instead of just laying on the coop flooring, or using the nesting boxes. So, what is up with that? I know I can't MAKE them, but.....??
