Honey farm is a common formation of four beehives and is one of the familiar fours. It can be made from one beehive by placing a cell in the corner of it, at the tip of it, or inside it. It also evolves from 7 cells placed in a row. It can be hassled in many ways.
In many cases, a block can eat a single beehive, but this is not the case for beehives from a honey farm. A fishhook can, though.
Four different ways a honey farm can form; other than the line of seven, all are common. The predecessors converge in generations 2, 4, 5, and 6 from left to right; this predecessor is shown in red at the top. However, the generation prior to it, shown in red at the bottom, is different for all four of them. (click above to open LifeViewer)
