Dear Bee-liners,
    Has anybody among you ever overwintered an observation hive indoor ?
 or are there any information, published or otherwise on this matter ?  we are
trying to overwinter 2 hives here in midwest (Illinois).  what would be the opt
imal temperature ?
     on a related matter, what is the minimal number of bees that is required t
o readily thermoregulate ?  50 ? 500 ? no idea.
     Any comment would be appreciated.      Yours  Zhiyong Huang.
