I got my chicks at 12 weeks. The first day we brought them in the coop they were scared, but curious. I stayed with them all evening. When it was time to roost they were clueless. I opened the little side door and put each chick in on the roosting bars. They were fine all night. The next night I watched them, again clueless. I did the same thing. The third night I just sat back and watched. They walked around looking up at the little door , trying to figure out how to get in the roost area. I finally got it! They would come down the ramp every morning, but had no clue how to go up the ramp each night. (I guess that's where the words " bird brain" comes from). I took each one and set it on the ramp in the up position. They slowly went up. The next night I watched and they went up alone. They are now 22 weeks and they go up the ramp every night. I'm in Texas so they roost about 8:45 each night.
