Mine are usually in there for a few hours. I find they lay their egg in 60-90 minutes and then continue to sit for 15-30 minutes after they've laid their egg. I figure they are just resting.
If I've opened the gate to let them out to free range and one is in the next laying. They will typically come out immediately after laying. They don't like to miss out on free range time.
