10 days ago I bought 6 point of lay pullets, 17-18 weeks in age. They are integrating with my other hens fairly well, except in the evenings. They are not using the roosting bars, but all huddle together in the corner of the house. They do hop up on the bars during the day, but don't seem to have got the idea of roosting at night. Am I just being a bit impatient or is there anything I should be doing to encourage them?
