I probably would have taken an entire hive but, I wanted to build them myself and - more importantly - the car was full. Now I need some descriptions of what a Dadant hive is supposed to look like and wide boards for the deep supers.
So, I cleaned out the entrances today. It was unnecessary almost everywhere but one hive was super clogged. So I guess it's good that I did it. I also added another 12.5kg of fondant spread over my 8 hives. And I found more mould on some of the covers.
