This is how I transition, from this point. Close up brooder/remove brooder, then at dusk, I move the chicks to a cage inside the coop for their safety. I do this each night until the chicks follow the older birds in - it surprisingly has never taken more than a week. My last group moved in in 2 days.I'm just not sure how to transition to sleeping in the actual coop/hen house. Should I wait until the May pullets are roosting and then round the chicks up and put them in the coop? If I take away the outdoor brooder then they'll need to sleep inside the coop/hen house.
