I LOVE LOVE LOVE puffy cheeked babies! You should get olive eggs out of that cross, hopefully...? I wonder what the birds will look like, though. EEs can be so pretty, and with the gorgeous Marans you've crossed with, I bet you'll have beauties. I hope your other chickie makes it out okay.
That rooster is GORGEOUS!!!
I also looked at Bev's site... she's got some really good information there (and linked) about Marans egg color.
I'm jealous of all you folks who are hatching right now!
