5.8. Queen cell production
This measure can be determined while the colony is being opened and measured for other strength metrics. It should be done after bee population measures have been taken. Every brood comb is shaken free of bees and examined carefully for the presence of queen cells provisioned with royal jelly and a larva. The cells are counted and then cut out for two reasons: 1. to prevent swarming (unless swarming is a variable of interest) and; 2. to prevent redundant duplicate observations on subsequent samples. For each block of the experiment this variable can be reported as sum of queen cells constructed per colony.
