See- "poultry netting".

Chicken wire, or poultry netting, is a mesh of wire, generally used for making fences. It is made of thin, flexible galvanized wire, with hexagonal gaps of 1 inch (about 2.5 cm) diameter, though chicken wire with smaller gaps is also available.

The term chicken wire in chemistry is used in different contexts. Most of them relate to the similarity of the regular hexagonal (honeycomb-like) patterns found in certain chemical compounds to the mesh structure commonly seen in real chicken wire.
