Well, ours have learned to use the ladder. They have an A Frame tractor that is approx 5 ft by 8 ft and 4.5 ft tall. With all this space, a roost, and nesting box, once they get up the ladder, that's where they stay all huddled together on a small 6 inch floor space where the ladder/door opens. I have put food at the opposite end of the upper level to coax them over closer to the roost to no avail. I have sprinkled treats in the same area hoping they would get fat and happy and just hop up to roost. As of tonight which is about 3 weeks into their new home, they still are cuddling together in a small corner above the ladder door. Silly chickens indeed:>
