>1. Why would a colony need this many drones?
Every fourth bee is 25% drones which is the peak of drone population in a normal hive.
>2. Can there be too much pollen in a hive?
Some people think so. You can move it all to the bottom box (it tends to be there anyway) or give it to splits when you make them to save them some work or freeze them for use in a pollen dearth in the fall so you get a nice batch of brood before winter when a fall flow fails...
>3. Now that swarm season is waning how much nectar-filling in the brood nest is normal?
I would expect the top of the brood nest to get filled, but there should be a large consolidated area of brood below that. If they are filling things here and there all over, I would be expecting to see them swarm...
