The Pain and Problem of Drone Laying Queens

I found another drone laying queen tonight, thats' the second so far this season (and a couple of other queens are also looking dodgy). It is a painful sight to see drone cappings across the brood for a number of reasons: although a result of the weather (KP!!) it makes you feel a failure; it means the colony is doomed unless you seriously intervene; it can wreck the comb; it can be difficult to find the queen (then you have to cull her!).
