I’ve noticed that one of my 3 hives has an unusually large number of bees above the top cover. I’ve fed them all sugar cakes and last weekend put a bit of pollen patty on just to top them up. That said, hive 1 and 2 are behaving the same, smallish lump of bees above the porter hole on the patty, all the sugar is gone. Hive 3 sugar is also gone, bees on the pollen but the top cover is covered in bees and they’re kinda noisy. Looks like it may be a decent day here tomorrow around 10C so I’m going to pop in for a bit. Don’t really like to open them up in January but I think it may be worth a quick look.
