Here is the story I had a small backyard flock of 3 RIR (each 1.5 years old). In early spring bought 2 light brahma chicks which are now 20 weeks old (but have not started laying yet). They were in an adjacent coop for the past 2 months separated from the older birds only by hard wire cloth and I let them occasionally free range together. The Brahma's had their own coop and had been using a roosting bar in their coop. When I merged to 2 "flocks" 10 days ago. The Brahmas (20 weeks and taller and heavier than the RIR) were pecked at a bunch but were able to get away in the enclosed run. They have never gone up into the coop to roost on their own. When I catch them and place them in the coop early evening when all the other go up to roost the Brahmas get pecked at and then come right out. When I do it late at night they stay there until morning. (I do not close the coop door as they have a secure enclosed run. ) I have caught them and placed them on the roosting bar for the past 5 nights but they will not do it on their own. It is not so easy to catch them as they hide in a hard to reach area under the coop. See pics (https://www.backyardchickens.com/web/viewblog.php?id=52843) . Today is merged flock day 10. Should I keep catching them at night and place them in the coop on roosting bar? Should I keep waiting and let it happen on its own? I expect the Brahma's to start laying sometime soon (hopefully) and I would like them to lay in the coop/nest box rather than in the sandy run Any and all ideas are welcome.
