Hi all. 3rd year beekeeping. Started 2 new hives this year. One is doing well. Just put my 1st super on. The 2nd one is not doing as well. The brood pattern has been "patchy" since the start and they haven't been as industrious as the other hive. I went out the other day and, although they are progressing, I came across this frame and I have no idea what is going on. I'm going to try to post an image (my first time, so I hope it works). If some of you more seasoned keepers could tell me what is going on here and what my plan of action is, I'd appreciate it.
