so i come home for work and bee's are out bringing in pollen. i go and take a 30 min nap. comeback outside and happen to look over at the hive and see more movement out of one of my nuc boxes. upon further inspection i noticed a big circle of bee's on the insulation. then i noticed that they had made a new queen and she was outside the box. i was stumped. she was small and i said wth is she doing out. and that's not the queen that i overwintered. i made a call to another beek, he said it could be a daughter. i was told to pop the top and look for eggs in a cpl frames not to do to much if there was another queen inside. nothing but foul brood is what i seen. 8 frames of foul brood and about 1 1/2 handful of bees left. i was so disappointed with what i had seen. this whole time my daughter was holding the queen while l took out all the bad frames and put in fresh new ones and a cpl frames of honey. it's now a single nuc and hoping it survives until mating season. i'm feeding it 1/1 sugar with honey b healthy. today i'm getting some tetramyacin, sorry for the spelling, and putting it on the frames and hope that it makes it. i will post pics later tonight when i get home. any suggestions on this and how to prevent this in the future.
