I sell hatching eggs but currently have a waiting list, and to locals, well, you'll have to wait until I hatch some eggs myself.
I have Black Coppers too if one is more into bold, dark coloration.
Black Coppers in most cases lay darker eggs than Wheatens and Blue Wheatens, but mine are usually tied for the darkest. However one must keep in mind, a Marans' egg color will lighten as the season progresses.
There's lots of others out there who have Marans, too. They're a growing popularity and for good reason.
I love the Wheaten, I was telling my DH about a hen that looked like a buck skin horse. It was somewhere I was driving and haven't been able to find it again. You found it for me THANKS
