I have a mixed flock of 7 (hopefully) pullets - 12 weeks old. At night, 6 get up to the highest roost via a lower roost that is about 2 feet off the ground. The BO cannot get up to the first roost, so we added a lower roost at about 6" to help to get her started. Of course, she won't use the "step" and wanders around at bedtime looking rather confused as the rest stare down at her. Each night I climb in and put her up high with the rest, only to find her still there at 6.30am each morning as she can't get down. Do I lower the all the roosts to accommodate her or start working on a ramp system so she can roost high with the rest?
