Eggsordinary

My wife informed me the other day that, just like last year, she had found some eggs that had been laid in our garden. Too big for Robin eggs etc, she reckoned they were duck eggs (we do get ducks using our pond from time to time).

I didn't have the time to look at the eggs at the time, but I did so today. Strange ... I always thought that the factory printed the UK size on the shell, not the ducks themselves.

Something strange going on here.
