New beekeeper here. I hived my package last Saturday and did a preliminary inspection yesterday. For some dumb reason, I evidently only put nine frames back in the hive so instead of putting the comb on the foundation, they built a large, oval piece of comb in the gap between two frames. No eggs or brood, of course, in fact it appeared completely empty. As I was holding the frame that the oval comb was attached to, it fell off landing on the top of the frames that were still in the box. Hopefully the queen wasn't in it. I did not see a queen or any eggs or brood in any other part of the hive, but I didn't spend a lot of time looking for the queen because it was cold and I wanted to just do a quick check and get it closed up again. I removed the comb and put the 10th frame in so they will have to start over. It's been cold and wet here (Minnesota) so I'm still feeding them pollen patty and sugar water. Because it's been wet, there hasn't been a lot of activity outside of the hive since the last sunny day, which was Sunday (the day after I packaged them). Any advice? Should I leave them alone to (hopefully) build on foundation? Should I open it back up once it's sunny again (this weekend) and try to make sure there's a queen? If the queen is dead, I will have to replace her and I'm not sure how late in the season I'll be able to do that. Are queens available through the summer?
