hey wombat what you will find is they are tooo high when you have 2 supers on that you will hurt yourself lifting the top one it can weigh upwards of 40kgs . The canies are less of a problem than the bee eaters with wings, you can not stop them.they eat lots of my bees but are also a beautiful bird so what do you do??hope you get lots of honey
then the fun bit starts,more gear another hive and so it goes.
