Start with 3-4 hens for a household of four, which typically covers daily egg needs with some surplus. From there, scale your flock using 4 sq ft of coop space per bird and never keep fewer than 3 hens, since chickens are social animals that need flock company to stay healthy.
Egg Needs by Household Size
| Household Size | Recommended Starting Flock | Typical Weekly Eggs |
|---|---|---|
| 1-2 people | 2-3 hens | 12-18 eggs/week |
| 3-4 people | 3-4 hens | 18-24 eggs/week |
| 5+ people or occasional selling | 6+ hens | 36+ eggs/week |
Egg counts assume roughly 5-6 eggs per hen per week during peak laying, which drops in winter and as hens age.
Space Math
Multiply your target flock size by 4 sq ft to get minimum interior coop space, and by 8-10 sq ft for outdoor run space if your birds won’t free-range. A flock of 4 hens needs at least 16 sq ft of coop interior and 32-40 sq ft of run space. See our full How Much Space Do Chickens Need guide for the complete breakdown, including nesting boxes and roost length.
Minimum Flock Size for Social Health
Never keep fewer than 3 hens. Chickens are flock animals with a social hierarchy (the “pecking order”), and a flock of just 1-2 birds doesn’t give that hierarchy room to function normally, which can lead to excessive stress on a single low-ranking bird. Three or more gives enough social buffer for the hierarchy to settle without constant conflict.
