My colony has been suffering from this disease for four months already, my colony is not getting weak fortunately, the broad area is also expanding, but I can still see many chalk mummies on may bottom board...
The set back is that I cannot use my colony for queen rearing and and I cannot let them draw combs because my colony my have more stress...basically chalk broad is a stress disease...
Chalk brood is one of the common disorders we usually encounter with our hives and a little less worrisome. It's a relief for you that colony does not regress (though that will not always be the case). Given your cold climate there I think it becomes conducive for this disorder to flourish. The advices given by fellow beeks above may work, have you tried them?
I am convinced, though, that this disorder is genetic, I mean, "passed on". In cases I have encountered, generally they never prospered. Even if they recover, or improved, I never did expect them to produce.
Dahil sayang din 'yong colony, you may maintain that for brood production, kahit konti lang. Magamit mo rin for introduction nucs for new queens. But as a breeder, no way!
If you want that colony to prosper and produce, the best thing to do (as suggested by Boch) is to re-queen. Take note where you got that, you may acquire queens with the same characteristic from the same source.
Given available resources, get rid of that.
