I have Show-Chins! They are eggs from mottled bantam cochins, crossed with a white showgirl rooster. These are the last of my show-chin eggs, because someone bought my mottled hens this week, every last one of them. I also have two silkie eggs from my blue and splash hens in with a black rooster. Also, three F2 eggs from my mille fleur cochin pen. They are $20/dozen for the mixed up lot. We are close enough that we could avoid shipping also, which should really improve your hatch rate.
Here is a thread about a recent hatch from someone who drove and got eggs. Fertility is excellent lately.

I also have fifteen Copper Black Marans eggs, which I know are not bantams, but you might like them also. Some are Bev Davis lines, with a big, very gentle blue copper rooster, not yet up on my web site, and some are from Wade Gene, Ron Presley lines. All are dark layers and nice hens.
As of this morning I have 15 of those eggs, and they are $5 each.
Edit to add, you can see pics of most the the parent birds on my website, click on the link under my avatar picture to the left of this post.
