Chicken coop & hardware cloth sizing calculator
Quick Answer: Standard heavy breeds require a minimum of 4 sq ft of indoor coop floor space and 10 sq ft of run space per bird. Always wrap run walls with 1/2-inch 19-gauge hardware cloth rather than chicken wire to prevent predator breaches.

Frequently Asked Questions
What size hardware cloth for a chicken coop run?
Most backyard keepers use 1/2-inch 19-gauge galvanized hardware cloth. It stops raccoons, hawks, rats, and foxes. Use 1/4-inch mesh on lower panels if weasels or small snakes are present.
How far should a hardware cloth dig apron extend?
A dig apron should extend 12 to 24 inches outward horizontally along the ground at the base of the run wall, pinned down with landscape staples or buried 2-4 inches under sod.
