I'd never heard of Thuringians before, but I think I'm in love!
I guess that means that's my vote.
The Marans would be my second choice just for their egg color, but of course that's only if egg color makes a difference to you at all. I don't have any experience with these breeds as bantams so I can't help as far as personalities clashing or anything, though.
Chicken math is a tough bug to beat!
All girls from here on would definitely be ideal!
