Hi...sorry just noticed your comment. Depends on which comb you are referencing. The dark comb shown at 1:52 is brood comb. Judging by the uniform size, I'd say worker comb. Drone comb is easier to spot when the larva is inside. You can spot drone cells by the way the stick out as shown in the image here: www.beekeepingfornewbies.com/wp-content/uploads/2019/03/Capped-drone-2.jpg The white comb shown at 3:01 is from the honey super so this is for nectar then honey. No brood expected in there.
