Mine at almost 16 weeks are not roosting automatically yet. Prior to last week, they huddled. Now, each night, I am going out after they go into the coop by themselves and putting them on the roost. The first couple of nights, it was a battle of the wills...I put them up, they hop right down.

. After a few nights and me waiting till it was slightly darker, I'm winning. I put them on the roost and they are still there in the morning. Next accomplishment will be that they get up there by themselves.
