The simple space rule
Backyard chicken planning starts with two numbers: indoor coop space and outdoor run space. The coop gives chickens a secure place to sleep and shelter. The run gives them space to move, scratch, and spend the day outside.
Recommended planning numbers
| Chicken size | Indoor coop | Outdoor run |
|---|---|---|
| Small | 3 sq ft per chicken | 10 sq ft per chicken |
| Medium | 4 sq ft per chicken | 10 sq ft per chicken |
| Large | 5 sq ft per chicken | 10 sq ft per chicken |
Example: 6 medium chickens
For 6 medium chickens, plan about 24 square feet of indoor coop space and 60 square feet of outdoor run space. If your yard allows it, extra run space is often the easier upgrade because it reduces crowding during the day.
When to add more space
Consider adding more room if your chickens are large breeds, your run will not have much enrichment, your climate keeps chickens indoors for long periods, or you plan to grow the flock later. A slightly larger layout is usually easier than rebuilding too soon.
Planning checklist
Before you make the final plan
- Confirm the flock size you are planning for now and the flock size you may want later.
- Check coop, run, feed, ventilation, cleaning, and predator-protection needs together.
- Measure the real yard space available before choosing a final layout.
- Use calculator results as a planning baseline, then adjust for climate, breed, and daily access.
