I was inspecting some hives today and one of my strongest hives with the most honey supers seems to have a brood disease. I am hoping it is not the dreaded foul brood. I noticed it most in drone cells. The caps were darker and when I started pulling the mummies out. The bee would move around a little but was darker than it should be I think. What does this sound like? Also looked like it is going to swarm. Found 2 capped queen cells. I was going to split it but now I am scared that I would just be spreading foul brood to more equipment.
