Which hatcheries did you find them at? I find some listed at Ideal and McMurray.
Ideal Poultry had three colors a few years back (Dark, Buff and White Laced Red), but I only see the Darks now.
McMurray Hatchery lists both Dark Cornish and White Laced Red Cornish.
Many hatcheries quit selling chicks during the fall and winter months, but they are usually available again in the spring and early summer. It looks like Ideal and McMurray are both following that pattern. If you want to be sure of getting chicks from either place, watch the websites in December or January, to see when they start taking orders for the year. Then place an oder and pick a ship date that works for you, even if the ship date is months in the future at that point.
Probably not the reason. If someone wants to re-create the commercial Cornish Cross, they can save a few decades by starting with existing Cornish Cross, rather than starting over with purebred Cornish and Rocks and maybe other breeds.
The current Cornish Cross breeding stock are very different than the heritage breeds that are their distant ancestors ("distant" being less than a century ago, but there have been enormous changes in that time.)
I think they are not being sold because not enough people buy them. Not many people buy them because they are not efficient egg layers, or meat producers. They don't lay eggs of unusual colors (blue or green). They don't have odd feathers (Silkied, frizzled, crested, feathered feet, etc.) They don't lots of fluffy feathers. They aren't a currently-exciting fad in color or breed.
So basically, of the things that will make people seek out a breed and buy it, the Cornish are pretty lacking across the board.
(Personally I like them: pea combs, not extra feathers to get in the way, attractive colors, nice solid build, brown eggs. But I realized a long time ago that my preferences don't match what most other people are buying.)
It's the same as sexing a chicken with any other kind of comb: the combs on males will get big and red sooner than the combs on females do. But the differences are most obvious on single combs, less obvious on pea combs or pretty much any other type of comb. So that makes pea-comb chickens a bit harder to sex.
McMurray Hatchery is where I got my White Laced Red Cornish. They only had WLRC not Dark. Dark was no longer available there. The other hatchery I found was Cackle. They only have Dark Cornish.
I think Dark are so much more beautiful but we live
on the surface of the sun between Las Vegas, NV and Death Valley. It's probably better that we have lighter colored birds to help reduce the likelihood of heat stroke. So far, we've not lost any birds from the heat but I spend a lot of time and effort out in the chicken yard ensuring they have areas of constantly wet/flooded land to walk through and plenty of water (though there is nothing I can do about the water being as hot as it is outside (110-120 degrees F), and shade. Today, October 2nd it's still 100 degrees outside. I can't handle the heat anymore.
I may need to order very early, like you suggest, and wait a few months for the shipment. Good idea. Yes, that was likely the problem of trying to find available Cornish. It was early summer when I ordered.
I'll consider buying some Cornish Cross birds and slow-feeding them, to see if I can raise them up to breeding age. I may switch from Bresse to Cornish Cross. We just processed our first three white ABC. We had them soaking in water in the refrigerator with just a TB of salt for four days. The bird I took from my mom's fridge had all floppy meat. It was quite minimal meat tbh, the color was lovely but... The meat was floppy. It was so weird. I ended up just bagging the parts up and putting them into the freezer as a meal for when I'm really low on food I can thaw it and cook it up. It grossed me out. They were 16 weeks when dispatched. Mom said her bird was just fine, not floppy. She doesn't even understand what I mean by floppy. It was very thin and literally flaccid, floppy, like it had no structure behind the meat. IDK. I'll wait another couple of months before I process any more of my ABC. Maybe they need much more feed than they are getting. They don't appear to be starving, in any way.
I seem to be similar to you in that my preference aren't what the majority of people are looking for in birds. I want good layers or good quick meat producers, friendly birds, birds capable of getting up and foraging for food long-term, birds I don't have to babysit to ensure they don't die of heart attacks, or get injured by just jumping down from a few inches...
I want sustainability and reliability.
The sad part is while those grocery store “free range” and “organic” eggs might be cheaper they are 100% sub-par quality compared to actual farm fresh eggs. I was raised on truly free range, grass fed and organic meats/eggs from our farm along with other local farms. When I moved out across the country at 18 I had to start buying from the store. I actually thought I had developed an egg allergy because every time I ate eggs I would end up with serious stomach pains. Someone mentioned that real farm fresh eggs don’t bother their stomach, but even the store bought organic and free range did. I picked up eggs from a local farmer and had no problems stomaching them. When I was in a financial position to buy a farm of my own I did right away. Now I raise my owns eggs and meat again. I haven’t had issues since and all of the stomach issues I had over the years are gone. We are now looking into raising our own lambs and my husband wants cattle for next year. The goal is to grow and raise all of our food.
Wow, I am so thrilled for you that you've found a way to eat healthier and be happier as a result! I have been pained by food allergies and intolerances my entire life. Come to find out I have Lupus and that's why I've developed all the allergies I have. I thought that if I raised my own chickens I would be able to eat their eggs. Nope. I can't.
I assumed that my allergy to wheat was causing the allergy to chicken eggs. And while that may have been the original cause of my allergy to chicken eggs, I still can't eat them even when I feed my flock wheat-free (rye-free, barley-free) feed.
But I learned that I can eat duck eggs without the terrible stomach pains. I now also raise ducks! I love my ducks more than my chickens. Ducks are hilliarous and happy, talkative, funny little birds. I still love my chickens but dang ducks are my go-to if I need a pick-me-up. All I have to do is stick my head out my door and yell out "hey duckies!" and they all start quacking up a storm and running toward me. They are the cutest darn things ever! My chickens may run a few feet then stop and walk away back to whatever they were doing.
I'm so thankful for you that you've been able to buy a farm and live a better, healthier life. It's fun expanding our capabilities, our mindset, and our skill sets. It's not without it's challenges, though.
