This is a materials planner. It does not determine whether donor colonies are strong enough to split or whether a specific recipe is appropriate for your conditions.

RESOURCE PLANNING

Turn your split recipe into an apiary-wide frame list

Different beekeepers build nucs differently, so this tool keeps the recipe editable. A Utah State Extension example uses a five-frame nuc with brood, food, and drawn comb; the important part here is that you enter the recipe you actually intend to use and let the calculator scale it.

Best use:Before opening donor colonies, know the total brood, food, comb, and box capacity your plan will consume.

Formula

Resource frames = units × frames per unit
Box capacity = boxes × frames per box
Spare allowance is rounded up to whole equipment pieces

Worked example

Five nucs built with 2 brood frames, 2 food frames, and 1 drawn frame each require 10 brood frames, 10 food frames, and 5 drawn frames before any spare allowance.

Reference

See Utah State University Extension — Splitting a Beehive for one practical nuc/split method and its resource layout. Colony strength and local timing still require beekeeper judgment.
