About Coop Planner

Coop Planner helps backyard chicken owners estimate practical coop space, run space, nesting boxes, roost length, and common footprint options before buying or building a coop.

The calculator is built for planning, not for legal, veterinary, or permitting advice. Local rules, breed behavior, climate, flock temperament, predators, and management practices can change what works in a real backyard.

How The Calculator Works

The tool uses transparent planning formulas and common backyard poultry guidance. It separates indoor coop space from outdoor run space, then adjusts recommendations for bird size, daytime access, climate, and future expansion.

Editorial Approach

We prefer clear assumptions, conservative planning ranges, and source notes from university Extension or education resources where possible. The goal is to help first-time and small-flock owners make better decisions before spending money on materials or a prebuilt coop.
