To feed or not to feed - Weston update

Hi
We have seen a lot more activity today and were worried that they'll pack their bags and flit but we think that we have some good signs
This was taken half an hour ago - they are coming back with pollen .

So my time this afternoon making a mikmon design feeder may have been a bit unessessary for today - is this the sort of thing that you have all made?
I've made it so that I can top it up from the non bee side and the bees have an entrance at the top of a follower board bee side so to speak.

And this is the side from the non bee side -

The little black bits in the feeder are drowned ANTS - we want to put ant powder down at the base of the hive but think that this may not be good for the bees - any ideas?

We are going to swap this over with the takeaway tray  tomorrow as we dont want to disturb them any more unless Dave phones or bloggs and tells me to feed them now !
All the best

Mike and Monique
