We have a rooster and 11 hens. We have for the past 2 days been opening the big gate to their pen and letting them free range a few hours in the evening. The rooster and most of the hens wander back into the own at around 8:30pm. A few stranglers seem to get panicky and start pacing on the wrong side of the face and can't seem to find the gate. Will they eventually learn or will we have to herd them in every night?
