| Conventional Cage | Metal cages (40‑60 cm² / bird), 2‑3 birds per cage. | Low labor, high biosecurity, easy manure collection. | Welfare concerns, limited movement. |
| Enriched/Perch‑Cage | Cages with perches, nest boxes, litter area. | Improves welfare, meets many market standards. | Slightly higher cost, still confined. |
| Barn (Floor) System | Deep‑litter floor, open‑air or tunnel‑ventilated house. | Greater bird freedom, lower capital cost. | Higher labor for litter management, disease risk if litter wet. |
| Free‑Range | Outdoor access ≥ 2 h / day, plus indoor housing. | Premium market price, consumer appeal. | Predator control, weather‑related management. |
| Organic | Certified organic feed, no synthetic meds, outdoor access, specific stocking density. | Highest price premium, niche market. | Strict certification, higher feed cost. |
