Why do Europeans not refrigerate eggs?

Excuse me, I've been wondering about a curious cultural practice I've noticed. Why is it that in Europe, people often do not refrigerate their eggs? I've grown up in a culture where eggs are always kept chilled, so this difference really stands out to me. Is it because of some kind of regulation or law that differs from other regions? Or is it perhaps due to the way the eggs are processed or packaged there? I'm genuinely curious to understand the reasoning behind this practice.
