I have arranged for an experienced beekeeper to go through my hives with me next weekend as I have seen so many things I don't really understand despite doing a 20-hour course, being on this forum, doing two apiary days and reading at least three books. I suppose it doesn't help, in some ways, thatone of my colonies is really, really big with at least six frames covered in bees and once opened, more bees spill out on to the tops and down the sides of the frames. Fortunately this particular hive is relatively docile but with so many bees it is difficult to see anything properly and really could do with a trained eye. The other hive is much less populated (in fact I've had to feed them today as they are short on stores) but they are too feisty to mess about with much.
Anyway, we'll see what my beeman says when he comes round. Will keep you informed.
