I installed 3 pound packages three days ago into a few different hives. I checked and all Queens were released. The hives are REALLY eager to work, they even pushed out the grass that I plugged the entrances with in order to begin their flights. I noticed 1 hive had a fair amount of drawn comb already and there were eggs laid as well. I saw a few cells that did have 2 eggs in them.

Can this be common during the first few days/weeks after an install, until things get, "settled?" Or....should I be concerned already about something bad taking place, such as a laying worker/ Thanks, juzzer
