I'm just now a little over 2 weeks in myself. I inspected on Friday as that was the end of the two week "warranty" on my queen and I wanted to be sure she's laying. I just pulled a few frames at random--and found larvae and a few capped brood. Interestingly enough, I seem to have the opposite problem of everyone else--every time I open the hive and pull a frame or two out, I find my queen! Lol. Today was no different, pulled frame 6 just to check for brood or honey and there she was...... :-D
Anyway, of the 9 frames plus feeder in the single deep I started with, they had drawn comb on all but the outer two frames on each end, and they were starting on those. So, today I added my second deep. I pulled a frame out at random (and of course the queen was on it!!!) and I found larvae, eggs, capped brood, and capped honey. So, I'd say we're doing pretty good. I may have put the second deep on too early, but, given my inexperience and the fact that it's swarming season, I figured there was no harm in putting it on too early as opposed to waiting too long and having them swarm or abscond.
I filled the feeder on Friday when I was in there, and today when I went to move it up to the new deep, it was only a 1/4 full. There's tons of fruit trees in bloom on our property right now, so I think I'd be ok if I stopped feeding, but, they seem to be doing so well in building lots of new comb and I just added the 2nd deep and they're still taking the feed I'm giving them, so, when I check on them again this weekend I'll see if they're still taking the feed or not and then try to decide whether I should keep feeding or not.
Again, bear in mind that I'm 2 weeks into this, so take my opinions for what they are.......
