Mine are 17 1/2 weeks and 9 weeks old. When I turned the light off inside the coop they stopped going in at dark. They hung out in the run and I had to put them in the coop. The last two nights I have put a light on and they have put themselves to bed. None of mine will get up on a roost. I have four roosts of varying heights and not one will go up, they all huddle together, under the light.
Then I have 5 week olds that will put themselves into their little coop before dark without assistance. They don't have a roost since they are basically still in the brooder, just outside in their own little area.
