The queens that came with the nucs are suppose to be hybrids of 4 bee types. Russian, Carniolian, Purvis Golden, and Canadian Buckfast. My question is, does a hybrid queen produce several different looking bees depending on what she was bred as?
Some years ago I had 5 different bee types and I let them cross. The result was quite awfull gang. Bees loose then features what we say "tame" or "domestic".
Hybrids are good bees but if you take daughters from these, the variation is from poor to good.
