March 4th: Good news: The hive looked very strong today! However, it looked like most of their honey stores were gone, so we began the spring feeding.
EDIT: We also noticed some comb building at the bottom of the frames... Not sure if that is normal or an indication of a pending swarm?
We inspected again on March 11th:
This time, there was quite a bit of comb up top too. The shot below shows more of this comb on the top. It looks like some had larvae.
We also cleaned out the bottom board. Here is what the gunk collected over the winter looked like.
