why?? not in a fridge?

It's the constant change of temperature when the door is opened as Superstar says. We have the lion mark to show eggs from healthy birds. Do you have this?

Yes, the British egg associations do too many campaigns. So, you're doing it right!
Thanks for sharing your experience.

Do you have the lion mark?

Well, I have lived in Britain, but never cared about the lion mark then. :)

I meant do you have the lion mark in your country?

No, not in India. :)
