🥚 Chicken Egg Production Calculator

Egg Production by Breed (Annual Average)

These numbers reflect realistic backyard flock output — not hatchery marketing claims. Production-bred birds in ideal conditions can exceed these; heritage breeds in mixed flocks often come in lower.

• ISA Brown / Sex-Links: 300–320 eggs/year — commercial layers, best for pure production
• White Leghorn: 280–320 eggs/year — high-strung but prolific, classic white egg
• Rhode Island Red: 250–280 eggs/year — reliable, hardy, dual-purpose
• Black Australorp: 250–300 eggs/year — record holders, calm temperament
• Barred Rock: 200–280 eggs/year — docile, excellent dual-purpose bird
• Buff Orpington: 180–220 eggs/year — goes broody frequently, calm and friendly
• Easter Egger: 200–260 eggs/year — lays blue/green eggs, very popular for farmers markets
• Black Copper Marans: 150–200 eggs/year — prized dark chocolate eggs, worth a premium price
• Silkie: 80–120 eggs/year — ornamental, goes broody constantly, not a layer

Winter tip: Hens need 14–16 hours of light to maintain peak production. A $10 timer and a single LED bulb in the coop adds 4–6 hours of artificial light and keeps production up through winter.
