I also let mine out after I feel they have layed. However mine have only been laying since August 29th, so some are laying and some are not. The other day I had let mine out and while I was cleaning the coop and surrounding areas I had one of my red sexlinks in a frenzy trying to get in the coop. So I moved out of the way and she went straight to the nest box and ended up laying an egg. It was after 4pm, I was sure that any of the ones laying would have done so by then. But I was happy to have her egg. I worry about letting them out to early for that reason also. But I stay with them when they are free ranging, so I don't think I would have too much searching to do if they layed outside of the coop.
