Soooo... I JUST happened to see a crow out of the corner of my eye land on Mum's lawn while I was watching a curling game. Yes, Canada won the briar beating Sweden in exciting fashion >;-). I wondered why it was where. It was walking toward the house. It strode up to the remains of a chicken egg... just pieces of shell which have been there for a while as I don't want to walk on the lawn until it is reasonably dry.

It picked up the largest piece of shell and flew into the maple in front of my house whereupon it ate the shell. Never saw anything like that before.
