Re: New package questions
Your populations will slowly drop for the next 3 weeks until you finally have new bees emerging (egg->bee = 21 days). I'd leave the entrance small until that point, and then I'd go to the larger reduced entrance. Maybe after another 2-3 weeks then open it up all the way if you want to. I've had hives with the larger reduced entrance all summer and they were quite fine. With the very small entrance you can get a bottleneck in outgoing/incoming bees. But the larger reduced entrance I don't think you'd see that except on super gigantic hives which wouldn't be a package its first year. Your call there though.
