Chalkbrood. How bad

[irishguy]

I done an inspection on my (over wintered nucs)hives yesterday and was worried about some whitish chalky brood on the last frame in one of the hives. I remember noticing it when opened up last week and TBH, im near sure it was there when i first bought the nucs. Do i get rid of all frames and start over again or just this one frame. Now TBH, it isnt much but its enough to get me worried, Id say about the size of a 20p coin so im wondering if it is CB, can i just cut the CB out.

Another thing, this hive is the one i mentioned about having the most dead bees under it and isnt doing as good as the other in another thread. I have a pic in my phone ill try and upload later.

If thisCB, what is my best approach to take now

Chalk brood is more likely to appear randomly, rather than in a clearly-defined cluster. Are you sure it's chalk? Perhaps mouldy pollen or some other agent? Unless a significant smattering of affected larvae, the bees may well sort it out for themselves, given warm dry conditions and hygienic behaviour. Chalk brood is more prevalent in damp conditions. The weakeness of the colony could be a consequence of another problem, nosema for example. The significance of many dead bees is a concern.

If you are in any doubt I would seek clarification from a fellow 'keeper or an inspector.
