Hello this is my first year into beekeeping and i am trying to overwinter 8 colonies 2 i made into a double nuc like mike palmer had in his video. BUT the others i am having trouble deciding on what to do for ventillation, i have inner covers with screened holes in them , but most are propolised shut and i keep digging them open. i know it's different for different places and i have read a lot on it and seen pictures of hives with different configurations. but i would love to know what is working the best for everyone?? we had mild winters lately and i am very worried about the moisture.

i did drill top entrance holes in the double nuc and it "appears" to be okay , but it's not cold yet either. : )

Any help or pictures you may have of your ways of dealing with this issue i would LOVE to see and read about.

Thank you
