I noticed one hive seemed to have a bit less traffic at the door so decided to have a look inside. Have been feeding two to one syrup for a week and a half on that one. Top box had 4 mostly capped frames and centre three had bits of emerging brood still. Mostly wet with thick syrup/honey. The lower box had about three frames about third full of capped brood and quite a few empty cells all polished. I had the hive back together before it dawned on me that I saw no open brood and only possibly a few eggs. Went back into the top where I thought I had seen the eggs but gave up as it is full of bees and I dont like to mess too much with them this time of year. I wondered if the queen stopped laying for a few days when it rained and I didnt fill feeders. Also have been getting down very close to freezing at night. They did not act queenless. I went into two other hives and pulled a couple of frames with capped brood and same story, the queens do not appear to have been laying for a while. I did not search the whole hives but no open brood apparent. These are not declared Carniolan bees but I think that is their main breeding. Can they be shutting down brooding to be in line with the stores ( hive weights, 2 deeps ~ 120 - 130 lb. Will they take a pause and maybe lay another round. There are empty polished cells in the lower brood.
