Apiary

Apiary allows you to breed bees. See the page Bees for details.

You can place 1 queen bee into the Apiary. It also has 1 slot for drones (up to 1000 of them), 1 slot for frames (up to 64 of them) and 12 slots for produced materials.

Later in the game you can replace it with Large Apiary. It has more slots for drones/frames/output and is more convenient for cross-breeding bees.
