I think the problem is that most folks are not willing to breed for anything but appearance because they aren't comfortable killing and eating birds that they have raised. I'm coming across more people that want to show their birds, so are interested in breeding to an appearance standard, but they aren't willing to eat one of their own birds at all. They wig out if you even talk about killing and eating a bird. It's part of today's citified society that is disconnected from the food supply.
I don't like the idea of the meat mutts from the hatchery because too many of them require you to go back to the source for more birds, rather than being able to have a self-sustaining flock for the long term. And the extra fast growing hybrids - well those are good for getting a lot of meat in a short amount of time, but again you're stuck going back to the source to get them because you have to kill them all at 8 weeks old before they start dying of organ failure.
There are birds out there that will do fine for a self-sustaining egg and meat flock, you just have to look at what your expectations are and then look for the birds.
We love our Javas and they do well for us. Even with just a handful of hens, we had more than enough eggs for us to eat and were able to share some. We aren't at the point where we can completely rely on them for all our chicken meat needs, but we're working toward that goal as well. Since they are dual-purpose, they don't have as much meat on them as a meat-only bird, and they grow a lot slower than a modern meat-hybrid, but we think that we will eventually find the right balance of how many we need to hatch and grow out each year in order to supply our meat needs. And our birds are hardy. They do well confined or free range. We did have to change our expectations a little bit to get accustomed to what a true, oldfashioned farm bird could offer us, compared to what we were accustomed to buying at the store.
You can find what you're looking for, you may have to alter your expectations or how far you're willing to go to get the birds you want, but they are out there.
That's what feels "off" about having to get hatchery birds each year, so you get what we feel. I think my husband is fine with buying from hatcheries because he's liking and expecting the high put-put and fast turn around of these hatchery hybrids, it impresses him to no end, and I get that. I think it's neat too. You get a tasty and big carcass in lightning speed from cornish crosses and we're on our second year with our ISA browns and we love their big eggs and vitality (can't stay that about these hatchery leghorns... they've been really hit and miss). But it still feels like we're having to depend on a grocery of sorts for food, and I don't want that! And indeed about expectations. We're coming to that realization that having to reorder egg layers every two years would be annoying. Interestingly, the ISA browns are still laying well though, even into two years. They're a decent bird. But I bred some this spring and they don't come true, even close to type. I've raised tomatoes from hybrids and usually even though they're hybrids they usually come somewhat close to type. These chickens didn't.
I'll keep looking out and researching, and thinking more on making my own bird. Thank you for the warm welcome!
