从传统的笼子转移到一个丰富的笼子或非笼子系统可能会影响安全或质量，或两者兼而有之，在这个新的环境中饲养的母鸡下的蛋。鸡蛋的安全性可能会通过内部内容物被肠道沙门氏菌血清型肠炎（肠炎沙门氏菌）或其他病原体污染而发生微生物学改变，或者由于内部内容物被二恶英、农药或重金属污染而发生化学改变。质量可能会受到壳、蛋黄或蛋白沿着完整性的变化以及功能、成分或营养的变化的影响。季节、母鸡品种、鸡群年龄和鸡群疾病疫苗接种状况也会相互作用，影响鸡蛋的安全性和质量，必须加以考虑。在大规模迁移到替代住房系统之前，了解这些不同的影响是谨慎的。
A move from conventional cages to either an enriched cage or a noncage system may affect the safety or quality, or both, of the eggs laid by hens raised in this new environment. The safety of the eggs may be altered either microbiologically through contamination of internal contents with Salmonella enterica serovar Enteritidis (Salmonella Enteritidis) or other pathogens, or both, or chemically due to contamination of internal contents with dioxins, pesticides, or heavy metals. Quality may be affected through changes in the integrity of the shell, yolk, or albumen along with changes in function, composition, or nutrition. Season, hen breed, flock age, and flock disease-vaccination status also interact to affect egg safety and quality and must be taken into account. An understanding of these different effects is prudent before any large-scale move to an alternative housing system is undertaken.
