This year I had about 40 production colonies and I started about 100 new colonies. It kinda looks like I may get decent enough survival this year (I'm tf) to have 100 or more colonies that could go into production this year. I have room for them, but my biggest concern is the amount of comb I have. Lets say I have about 6 boxes with comb for every production colony from last year, and about 15 frames (all mediums) for each nuc I had going into winter. Generally speaking I like to keep my overwintered hives, but is there a rate of expansion on a percentage basis that commercial keepers would be comfortable with to avoid problems with swarming in their operation?
