I probably make 50 to 100 mating nucs most of which build up into nuc by the end of the year. I've never moved a nuc 3 miles away to get it started. I never had a PLACE three miles a way to get it started.
I just shake in another frame of bees from oepn brood and figure half of them will go back home. I've never noticed that it set off robbing.
A DEARTH will set off robbing. Feeding the nucs will set off robbing especially in a dearth and especially if you don't feed the strong hive as well. I try to give the nuc enough stores to last a while. In a medium two frame mating nuc I give them a frame of honey and a frame of brood.
