Successful re-queening and sugar syrup feeding

I'm ought to update on the re-queening of CGB-3 colony.

After a week I inspected the hive and found the Queen still inside the cage with lots of bees inside with her. They didn't want to let her out for some reason. When I inspected all the comb I found the reason for her being kept a prisoner; I found couple of fully drawn Queen Cells!
Since it's already August there is no chance these new Queens would mate properly because all my hives have already evicted all the Drones. For this reason I destroyed the Queen Cells and released the Queen which was immediately accepted by the worker bees.
I checked again on this colony after 5 days and found eggs and larvae fed with Royal Jelly. Will have to look again soon to see if the brood is capped and if there are any new Queen Cells present.

I have down-sized all the colonies to 10-12 combs and removed the rest so to keep the nest as small as possible. Buckfast colony needs max 20 kg of stores to survive the winter. To be on the safe side I started feeding sugar syrup (sugar 5:3 water) behind the follower board using inverted jars.
I strongly feel bees are to winter on their own honey and for that reason I only harvest after the 11th or 12th comb and only once a year at the end of July.
I feed sugar only to make sure bees are going into the winter filled up with stores. Will feed until they stop taking in the sugar syrup. Conventional beekeepers remove all the pollen stores believing that it goes bad but I strongly feel that feral bees keep their pollen stores and if not I will rather like bees removing it, since they know what it is to be a bee colony, I don't ;)
I do understand beekeepers removing all the pollen in localities surrounded with large scale agriculture where pesticides are being used, especially so if Neonicotinoids are being used which are known to cause CCD (colony collapse disorder). Such pollen and nectar/honey is polluted with systemic pesticides, highly poisonous to bees.
In my locality no one use Neonics only Round Up at the end of Autumn. They do this to kill all the Thistles and Dandelions on their grass fields so to get a better quality hay for their horses and cattle.
