Chuckle. If you're interested in new bantam breeds, take up Sizzles. The genetics are challenging, hilarious and we're already working on the breed. I have several sixth generation Sizzles now. There's quite a large group taking it up. I have blue/black/splash and working on a Birchen line as well, but it's further behind, as my male had significant cochin features instead of silkie ones. But my sixth generation kids look nice, so I'm getting there. This year I go back to Silkies to get more type. Then back to their progeny this fall.
I'll be at this for years. I enjoy it. And it will be years before we have enough of a genepool and people interested in showing to do APA shows for acceptance. But you can work for six or ten generations to get even a few dozen birds that really meet a show standard consistently. That's a LOT of space, time, feed and money, as you have to raise EACH generation to full adulthood to judge type, then you toss out what doesn't fit, and try with what comes close. Meaning you hatch near year round, working for two or three generations a year, with any luck, rearing many many chicks, only to sell most off at a loss.
If you want to get into a new breed undergoing acceptance RIGHT now - look into Marans. Also a breed being worked on but should be accepted next year by the looks of things.
If you love a breed, it's worth the effort. I happen to love Sizzles and Sizzle genetics, so I'm in. I've even got a couple of marans. My main group are Delawares and my layers are Rocks (blue black and barred). But I don't combine them at whim or pretend mutts are anything but mutts.
Establishing a breed is serious business, takes years and is lots of fun, if you're into that kind of hard work.
I do sell off mutts when they happen and they make good layers or chicken dinner, but a first generation cross of anything is just a mutt. Four of five first generations only creates a very confused looking chicken. It will still lay, or still be meat, but it's a pet, not a purebred.
Breeds happen deliberately and slowly, you document, you set type, you cull birds that don't fit the type, you breed again, and you repeat that for years. You keep records. You feed a lot of birds that just get culled. You shovel a LOT of ----. For something you love, that's all just part of the deal. For a whim, it just sucks.
