I lost my 2 hives of Italians last year. I am buying more Italians and am also trying a hive of Russians. I heard the Russians are ornery but good producers, does anyone have experience with them? Are they prone to robbing - I had a problem with the Italians cleaning out the honey in each others hives last year, as well as superseding the Queens - I went through 5 Queens for 2 hives!?
