Do your bees move the syrup from the filled syrup frames into the broodnest?
The hive is feeded so that you may feed part in the middle of August. Then hives are still full of brood. At the start of September there is no larvae because flowers do not give pollen. Then last brood emerge.
Now, you´should give the last feeding that bees fill the empty brood cells.
If the colony is pressed into one wintering box, it happens with the aid of excluder.
The queen get only one box to lay in August. So do the professionals.
I let them lay as much as they like. Just now I move all brood frames to the lowest box and extract the honey. Now bees still need 2-3 boxes but summer bees are dying with huge speed.
I take all honey away and reolace it with sugar syrup. On average bees consume 20 kg per hive.
This happens at the level of Anchorage.
in large USA you have many kind of beekeeping habits but I cannot see, why you do all those tricks.
At least at hobby level proceduals are really odd.
