chalk brood

[mat]

I noticed some chalk brood in one of my hives. How contagious is it? Can I use empty (without brood) frames from this hive in other ones? When they clean all the "mummies", what they do, can I unite them with another healthy hive?

don't worry about it if it's just a bit.  i had some and so did a couple of other people on the board.  warm weather and good ventilation took care of mine.  i have a sbb and cracked the top open when it wasn't raining.  have not seen any sign of it in weeks.

if you have a lot of it, the general CW is that you requeen.  there are mixed reviews on that.

i used drawn foundation from the chalkbrood hive in others and have not seen signs of the disease in other hives.  it doesn't seem to be to big of a deal if you can get it under control.

Thank you for your response. I was thinking about uniting with the nuc with better queen. It would help even more.
