To eat eggs which are six days out of date?

[BertieBotts]

BF says I am and wants to send me to the shop for new ones. I say they are fine as I have tested them in a bowl of water where they stood on end, which I have always been told means they are fine although it's better if they are cooked through, and have always eaten eggs like this and never had one which was off. It's for scrambled egg so will be cooked through.

I had one ths morning soft-boiled that was 13 days after best before, It was fine, I am still alive so far.

I get cheap eggs from the parents of one of my pupils. They have a free range farm and sell us the 'seconds' - eggs where the shell is too thin or rough or not quite the right size. The 'good' ones get sent to the USA. We are in NZ, so heaven only knows how old they are by the time they are eaten.

I have had one off egg and I certainly knew about it.
