🍯 Single vs Double Brood Box Management

A side-by-side 3D cutaway of a single-brood-box hive and a double-brood-box hive, showing how comb space, congestion, swarm-cell risk and winter stores change with colony population.

Biology & Life3DModerate60 FPS

Two identical colonies, one on a single deep brood box and one on two stacked boxes, are shown side by side so you can watch how comb space alone changes congestion, swarm-cell risk, honey stores and winter survival odds.

🔬 What It Demonstrates

The same population is applied to both hives at once. Occupancy, queen-cell formation, honey stores and winter stores runway are all computed from how full the available frames are — the single box hits its ceiling at roughly half the population the double box can absorb.

🎮 How to Use

Drag the population slider and change the season to watch the comb heatmap, swarm-cell overlay and winter cluster respond on both hives simultaneously, then compare the dashboard numbers underneath.

💡 Did You Know?

Congestion, not population alone, is what triggers the swarm impulse — a colony that would be comfortable in a double box can feel dangerously overcrowded in a single one during a strong spring nectar flow.

⚙ Under the hood

A side-by-side 3D cutaway of two identical colonies — one on a single Langstroth deep brood box, one on two stacked boxes — where population, season and comb-space capacity drive live changes in comb-content heatmap, queen-cell (swarm) formation, honey stores and winter cluster behaviour.
