Great thread, glad I found it before I posted it. I'm having the same problem with my 4 almost 3 month old RIR's. They don't even care if it's raining, they still stay outside in a corner of the fence all piled on top pf each other.
I just figured out it was the light a couple of nights ago. So now I turn on their heat lamp just before dark, and they all go inside. I didn't have this problem with my EE's last year when they we're old enough to go out with the grownups.
It will be interesting to see what other's have to say about this problem. Good luck with your's. Hey, at least we figured out it was the light causing the problem.
