Maybe Henry's vision is failing? Lucy, my oldest hen (she's a out 8 now) started roosting earlier, and earlier. After a while, I realized she wasn't seeing so well any longer. I think now, about 2 years later, that she is almost completely blind. She lately does this head bobbing thing before she jumps onto the roost. The others lead her to the waterer and feeders. Her rooster, who is her grandson, rounds her up and keeps her close to him. It's sad because she was the top hen for most of her life. No one is mean to her, but she has lost her status.What Molpet has written below.
I think if I wasn't there the hens while perhaps not going immediately to roost would stay close to the coop. They stay fairly clos when I'm there anyway. Funnily enough tonight Carbon saw the rat again and had a bit of a rant at it and Henry came back out of the coop to investigate.
Henry finds getting on to the coop extension roost bar difficult. For some reason he is reluctant to fly up directly from the ground. Instead he climbs the coop door ladder and makes a rather untidy jump onto the roost bar. I'm going to try to make it easier for him but I'm not sure how yet. There is enough room to jump. There was less room on the outside bar at the old coop and he made that. But, there was a box thing below the bar and he did use that to make the climb.
