The queen in my observation hive is acting strange. She was doing good,laying eggs, looking for empty brood cells and had a group of attending bees following her around. Now she scurries across comb in a mad dash and other worker bees seem to harass her, grab on to her and even chase her across comb.There is also not much new brood due to lack of brood cells or because they are filling with nectar. Whats going on here. The observation hive was concentrated at the top due to cold weather and that's where syrup was being fed. They started making queen cells I think b/c they thought they were running out of room. We removed queen cells and moved brood to bottom of hive hoping they would start working up to fill empty frames. In any case this behavior started before we moved frames or got rid of queen cells. I don't know if we did right thing or not but this odd queen behavior has me wondering what to do if anything at all. Looking for some advice as I am new beekeeper.
