Note, the egg on the right is the first egg, the one on the left, the second.
How do I know this? I watched Hazel poop on the first egg as she laid it. Think the whole biology of egg-laying came to quite a surprise to her.
She's very different from Princess who I watched the longest laying eggs - Princess used to keep her but down and you only knew she'd laid her egg when her tail would pop up afterwards. So far with Hazel, she stands up tall (and she seems bigger than Princess or Ella) so her egg drops a couple of inches down onto the gravel. Yet another reason why the gravel works, even after such a dramatic entrance, they haven't so far, rolled afterwards. Makes knowing she laid an egg easier but it makes one wince a bit as the egg drops.
