Installed a new package on 27 April, and release the queen at the same time. Reason why is because there were a lot dead in the bottom of the package and I thinking they have been together a while. I know I should have waited a few day before releasing the queen but the first part of the week I would be leaving early and getting home late. My question is even though I saw the queen walk into the hive I'm still not sure if she is there, how long will it take before she start to lay, and when should I be able to see larvae? If she not what should I do?
