We have Belgian d'Uccles. They're sweet, goofy birds. We also have mutts: mixtures of Serama/d'Uccle and Old English Game bantams. You wouldn't want Seramas because they aren't cold hardy, but the Old English Game bantam breed might be a good choice. Compared with the d'Uccles, the OEGB are sleek, elegant birds. They come in a dizzying array of color choices, too.
Rather than ordering from a hatchery, google around to see if there are any backyard breeders in your area. If your Ameraucana hens show any signs of going broody this spring, you could get some hatching eggs. Now, that's fun, to have your own hens hatch and raise chicks. To test if your hens have any broody instincts, you could just stop collecting eggs for a while to see if one of them decides to sit on them. You''ll know you've got a broody if she sits on the eggs overnight, and fluffs up and growls at you when you approach her.
When you hatch your own chicks, you do have to deal with the little cockerels that might result. We hatched our own last spring, and it was an amazing experience I wouldn't have missed for the world, but it was very sad to have to give away the cockerels (it's against the law here to keep roos).
