it is very important to undestand the entire system of epicalture especially the supercedure process as it is naturally done by the bees. colony splitting is very much possible . however before you artificially do the splitting, kindly ensure that you give the bees time to have it done naturally. coz when the colony is to big, there is anutural way i which the bees themselves starts preparing a new queen to take over the next colony that they themselves will split. you only have to provide empty hive and you will have it colonized when the time is appropriate. should something goes wrong while doing the collony spliting artificially, you risk having the bees abscond hence lossing the entire apiary coz they can relocate or fight
