Chanteclers.
And I think it would be fun to put a beard/muff on Chanteclers. You are already breading Buff Ameraucanas, which could do this on Buff Chanteclers. I would love to see other colors also in Chanteclers, with beards.
I have just started some chicks in Buff and Partridge. I love them already. Breed has great characteristics - tiny cushion combs, do well in the cold and will walk in the snow, mellow chicks, good homestead bird for laying, meat, and some broodiness to keep chicks coming. I was thinking of crossing the cushion comb into my Easter Eggers to reduce the size of the comb on the roosters.
After reading the Chantecler thread here on BYC forum, I ordered them from Ideal. The folks on the thread said Ideall's have good form and type for hatchery birds, only have to work on size.
I have BBS Ameraucana but don't know what the color mix will turn out to be.
