Re: Trying it again-one question
Broodless cell starters are normally blocked in, queenless and broodless hives are prime targets for robbing. Below is a pic of a fairly stock standard cell starter box, often called a swarm box even though they are not typically used for swarms. Note the mesh along the two lower sides, that's to ensure adequate ventilation, as the bees are not allowed out.
If you want to leave the cell starter open, the other way to do it is remove all the brood & queen from an existing hive, then shrink all the bees down into a tightly packed cell starter. Because they are on site they will retain the older bees that do guard duty.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
