I'm checking the top bar hive daily now to feed and have noticed that all the dead bees are gone from the bottom. The bars are set now to accommodate the expansion and contraction with moisture without closing up the entrance, so I'm leaving just the top entrance as is.
I pulled a few bars to check the comb building progress, and the comb is absolutely gorgeous! Now hoping that on next inspection I will see eggs and larvae. Just a few weeks into the TBH experience is much more pleasant than my first few weeks with a lang last year. That said, I'm sure I'll find something else to worry about soon
