How Big Should a Chicken Coop Be?
Designing a chicken coop requires careful planning to ensure your birds remain healthy, productive, and stress-free. One of the most common questions among backyard chicken keepers is how much space each chicken actually needs.
This calculator helps you quickly determine the ideal coop size and outdoor run area based on the number of chickens you plan to keep.
Minimum Space Requirements
As a general rule, chickens need between 0.3 and 0.8 square meters per bird inside the coop. The exact requirement depends on how much time they spend outside and the overall setup.
For outdoor runs, chickens typically require 1–2 square meters per bird to move comfortably.
Why Space Matters
Overcrowding can lead to stress, aggressive behavior, feather pecking, and reduced egg production. Adequate space allows chickens to exhibit natural behaviors like scratching, dust bathing, and perching.
Coop vs Run
The coop is where chickens sleep and lay eggs, while the run is their outdoor area. Both are essential for a balanced environment.
Real Example
If you have 6 chickens and choose a standard setup, you may need around 3 square meters of coop space and 6–10 square meters of outdoor run space.
