When I got my new job our lives got immensely busier and we became too preoccupied to check in on the bees. We figured the only thing we were missing out on was a harvest of honey. However it seems we also missed out on seeing if things were going ok inside the hive or not. Now it's too cool to really check it out.
One day in October dark splatters started showing up on the outside of the hive. After consulting with other beekeepers it seems that our bees have dysentery most likely due to Nosema. We could medicate but for now we have decided to keep medications out of the hive. That and we didn't really have the time to apply the medication and figured we would just ride it out and see what happens.
It is warm enough that a few bees have been seen outside the hive. I am hoping this is a good sign.
