Sorry, but Carbon Dioxide (CO2) weights 44 units (C=12 plus O=16 - twice
i.e. 12+16+16) and the air (a mixture of various gases) mean weight is 29
(at 20 degrees C or 293 K). CO2 is really heavier at the same temperature.

Also there is known that gases encrease/decrease their volume by 1/273 to
each Kelvin (Celsium as well) temperature degree. Let's take the difference
of ambient temperature inside a hive is minus 60 K (or C) if compared to
bees inside temperature. Then the breathed out CO2 will increse by 60/273
i.e. 22% or its specific weight will decrese by 22%. That's 44/1,22=36 units
and this is more than 29.

If there is no moving/mixing  force (wind, bee fennig with wings, maybe,
thermic streams, etc) these gases distribute according to their specific
weight.
