Maybe a second tree for the bees is a good option? I play Hay Day alot, but my honey machine is not always working, because I think have not so many bees (4 hives = 12 bees). Maybe a second Beehive is a option, so we can have twice the ammount of bees as now. Maybe just like the first tree you have to harvest XX honey to have more bees on the (second) tree.
