One pair of Wheaten Marans started eating their eggs. Naturally it was Wheatens, those are the ones I'm getting the most hatching egg orders for.
Further proof of Universe Vindictiveness is, this hen produces some of my darkest Wheaten Marans eggs.
There's a reason I keep around piles of lumber scraps and stuff like that. I put together an anti-egg eating cage out of what I had laying around, and it didn't take but a short while to put it together.
Side view shows how it slants from front to back. The whole lower half is covered with carpet scraps to protect the eggs from breaking.

The hen enters the "nest box" here.

And the egg rolls out here.

It's working very well.
