I occasionally get an egg with a hazy halo in the white around the yolk.  Has anyone else had this or know what causes it.  It seems to be the same hen that lays it.  It's fresh & not off and doesn't taste any different.

This is the best guide to egg quality that I know.  On page 16 it says:

In a very fresh, good quality egg, the albumen is jelly-like and may
have a cloudy appearance. As the egg ages and carbon dioxide
is lost through the shell, the contents become more alkaline and
this causes the albumen to become transparent and increasingly
watery.

Ooh :!:   thanks for that Auntie.  I was worried and it sounds like it's a sign of freshness.
