Six days after install and I was lucky enough to have about 80 years of beekeeping experience there with me, (my coworker and his 86 year old mother). We were 15 feet from the hives and she saw workers bringing in pollen before I got within 5 feet! According to her, that means you have a laying Queen.
We saw eggs and loads of pollen being brought in. The one queen we did locate was very young and active.
I don't know how large the eggs are when they are laid, but I saw them today. Not much bigger than a comma in a newspaper. Nice laying pattern, and lots of comb being drawn. Lots of activity on the outer frames. Since this is only the second day of nice weather they have had since install, they are doing really great. I'm pleased.
