Space Requirements
Beyond Minimum Sizes

Espaço

Interior: 0,5 m² por galinha. Área externa: 1-2 m² mínimo. Ninhos: 1 para 3-4 galinhas. Poleiros: 20-25 cm por galinha. 6 galinhas: galinheiro 3+ m² + solário 6-12 m². No Brasil, galinhas caipiras são tradição no interior — o ovo caipira é muito valorizado.

Produção

Boas poedeiras: 250-300 ovos/ano (5-6/semana). 6 galinhas: ~4 ovos/dia — suficiente para família de 4. As raças mais populares no Brasil: Embrapa 051, Rhode Island Red, Plymouth Rock.

⚡ CalcWolf Insight

Backyard chicken economics: 6 hens produce approximately 4-5 eggs per day (1,400-1,800 per year). At $5-7/dozen for free-range eggs, that is $580-1,050 worth of eggs annually. A basic coop costs $200-500 to build, feed costs $20-30/month. Most backyard flocks break even in year 1 and produce "free" eggs thereafter (plus entertainment, pest control, and garden fertilizer).
