Quail eggs are amazing in that every single one is unique. They have a beautiful brown and white speckled pattern that is different on every egg.
Your eggs should have:
1. A strong shell with no visible cracks, holes or weak spots
2. A beautiful light brown or off-white colour with brown spots or “speckles,” with no dark rings or spots. Anything that looks solid brown or overly white shouldn’t be eaten.
3. A fresh smell, similar to what fresh chicken eggs smell like. If they smell funky, leave them be.
