I did my first inspection of my first hive this past Saturday (one week after installing a package). I have to say, speaking as someone who really hated biology and science back when I was in school, I'm really finding this venture fascinating so far. I was amazed to see how much progress they made in drawing out comb in just a week.
That empty spot in the middle of the frame is where the queen cage was sitting. I'm assuming they'll fill in the gap now that it's been removed.
And another view of another frame:
