My bees are very active at the moment also, pollen loads going in galore.
Both my colony's very busy.
I have my feeding over , with my strong colony, they stopped and wouldn't take any more, a few weeks back.
My other colony are in a poly nuc, and still feeding ,but they have slowed right down on taking it, so id say they will be done with it this week.
I like getting my feeding over before a cold snap, gives the bees sufficient time to evaporate any excess water.
I would suggest that you check their store situation first.
If they are low, then feed.
Everyone is different, some feed, some wait, some don't feed at all, if the bees have enough of their own stores.
Check first I would think.
