LOts of activity today, orange pollen being taken into both hives.
Hive 1: removed contact feeder and nadired super, which was empty and nicely cleaned (thank you girls). Found during quick inspection that the brood box was almost full - six brood frames and four stores - so I plonked the empty super on top above a QE. See below for my thoughts on feeding. No sign of disease.
Hive 2: Feisty as usual. Far as I could tell, as they're hard to inspect with my every move prompting a fresh cloud of bees to buzz around my head and bang against the veil, there are three frames of rather patchy brood and about two or three frames of stores. So I removed the contact feeder and left them to it; they've enough stores for the next 10 days or so, I reckon, especially since ***** willow and red currant are now out here. No need for a super as there's plenty of room.
