Ive done something similar, given each hive the name of a flower, i was also thinking about placing a sticker or a blob of paint on the equipment which belongs to that one colony, so i avoid cross useage.
Have yet to decide what i will do.
Does anyone else do this ? or is it just Admin & I.
For a few days before I put a nuc in a shed this autumn (sorry fall for you N Americans!) I stuck a white triangle on the brown wood of the nuc and then put the triangle above the hole in the shed wall after I moved them to help them find the correct spot easily. Not sure if it did any good. The triangle blew away a few days later in any case.
I've "branded" my hive bits with a red hot nail:-
F1 = floor hive 1
EB 1 entrance block.
B 1 Brood 1
R 1 Roof Have not bothered with supers yet because they are all new and will be marked as they are added. Pictures later if I can work out how to post them
