Got a nuc and come to find out that it has chalk brood. Took about 1/8 - 1/4 of a cup of mummies off the bottom board, a week after it was made up. The nuc came from "over the mountain" where it has been a cooler and somewhat wet spring. Frames were pulled from a hive requeened this past Fall.Having never had this before, and understanding that it can clear up by itself (although I wish we were not going to have rain all week), I have a few questions:
Can chalkbrood spread within the apiary if you do not move frames around?
If it clears up within a few weeks, would you still requeen?
any other advice on dealing with chalkbrood?
