I'm going the small cell route and have started to take note of the various sizes. My new swarm built some comb from scratch and it measured about 6.2. It had a touch of honey in it and was built in an empty hive body I sat on top of a lower. I suspect this would have been used for food and would have been a little larger than brood. I measured some natural brood comb I got from a likely first generation feral colony. It was about 5.2. This 5.2 reflects what I've read about the first regression to natural size. What I'm looking for is a comparison of cell sizes of standard, regression(s), and natural. From what I've read brood goes from 5.6 to 5.1 to 4.8ish. What about drone and honey?
