Keeping them separated until about 17 weeks, when they can eat the layer feed, seems to work well for me. The grow-out pen is a fenced off portion of the main run, and when the 17 weeks is up, I just open the gate and they start mingling with a few pecking order issues that are to be expected, but they are pretty much the same size by then, so no real damage is done.
