Pollen coming in; how good an indicator is this of a new queen laying.

[Moobee]

I'm just wondering if anyone can hazard an experienced guess on the percentage chance of this being evidence that I now have or am about to have a laying queen.
A queen will have emerged from a cell in the hive five or six days ago and we've had settled, but not glorious weather since then. The bees have been in that slightly listless state for a week or so with no pollen coming in. Yesterday afternoon they suddenly sparked into a healthy frenzy of activity to the extent that I became concerned that they may be being robbed. Today they're suddenly bringing in neat parcels of pollen.

I had a small hive requeen recently and had left them alone for several weeks while I hoped she had successfully hatched, mated and started laying. Activity at the hive entrance went from occasional pollen gathering to a sudden burst of activity and they were excitedly all over a large phormium gathering pollen and dashing back to the hive. When I inspected there was a lovely new queen laying her socks off.

I'd agree, having had two nucs side by side and one with a queen and one without, the activity and amount of pollen collection was radically different. From a few collection pollen to most collecting. When I sorted out a queen for the second, activity and purpose were indistinguishable. Obviously caveats, but sounds promising.
