Voracious feeders

Went to the hives today (I'm up-to-date now!) to take out the porter bee escapes and cover the holes in the crown board with some wood (whether this is a good idea or not is not clear: Patrick said to cover them, others say to leave the hole open for ventilation - I've covered mine for now). As I did so, I saw that the feeders were both running quite low. I had been told they should last a week. No way! Probably due to the useless weather, the bees are gorging themselves on the syrup and it's going down like whisky with an alcoholic.
So I bought another 4kg sugar and made some more syrup tonight, which I will bottle tomorrow and have on stand-by.
