Here in Anchorage, Alaska I have very rarely had a spring without some
Chalkbrood. It is cool and damp in the spring. I have yet to have it
amount to anything when the population built up. I am refering almost
exclusively to new packages. I usually start about four new packages
each spring, and only rarely have had any real success getting any
significant colony through until spring.
Unless bees showed a problem with Chalkbrood I would not be concerned
about it.
