Is'nt carbon dioxide more dense than air?
It would rise slightly from the heat given via bee repiration but would
then fall once it equilibrated with the temperature of the enclosure. At
any rate the convections and mixing of the gases within the confinement
would be controlled by thermal gradients produced by changing temperatures
and pressure changes from external winds (breezes). Kind of like baseboard
heaters and the movement of the surface of the toilet on a windy day.
Just my perspective. Mike
