I haven't any answers to your questions as I am just a perpetually perplexed second-year beekeeper, too. But I'll second the feeling of not really having a handle on my hives' activities and needs. And I thought the first year was bad -- the second year seems even more nerve-racking as I know much more about the potential pitfalls, but apparently even less about what to do about them than I did in my first year. Wonder what the third year holds in store!
