Had to make a split with a queen and a few frames earlier in the week to prevent a swarm.
I moved them to a Nuc box on a nice day, but the 3 following days were fairly cold and rainy.
When I inspected the hive today I noticed a lot of streaking on the front of the hive, as well as inside.
The parent hive has no signs of dysentery.
Could this be a potential problem and what can I do about it?
