There's Whiting True Blues, @TexasBlues has a thread with videos of them and Marans that's super cool to follow as they grow. https://www.backyardchickens.com/threads/%F0%9F%90%A3%F0%9F%90%A5black-copper-marans-and-whiting-true-blues-lots-of-videos%F0%9F%8E%A5.1607191/page-8#post-27463804
I would suggest adding color to your egg basket...
Chocolate, Blue, Green/Olive, Pink?
And Speckled eggs are always a lovely sight.... 🙂
Unless I missed someone in your flock you've got all brown eggs.
