We are building a no-dig garden (it wasn't my idea). It involves alternating layers of straw and poo. In one bag of chook poo there was an intact egg. It weighed almost nothing. It was probably very old. I accidentally stuck the spade through it. It didn't just break; it went off with a BANG. This dark grey slimy substance oozed out of the egg, which was bad enough, but nowhere near as bad as the smell.
If you choose to find an analogy here with England's campaign to retain the Ashes thus far, well, that's up to you.
