Certainly sounds like Cornish X, but remember they're a proprietary hybrid from commercial hatcheries - local breeders would only have them if they're reselling. And F1 won't breed true even if both parents are Cornish X, so no one can just reproduce more.I'm doing a meat-hybrid x layer-hybrid cross. I've been in doubt wether the meat-chickens around here is what most people would call a cornish-cross. Reading on weights here on BYC and general growth rates, I'm starting to think they were. I kept 2 roosters for breeding to my brahma's. Their sister (I wanted hens for the brahma roosters but ended up with boys) dropped dead at 4 months and that was a very wide and plumpy chicken, another reason why I think they actually were cornishX. And indeed, the bigger one of the 2 roosters didn't fertilize a single egg. I have since learned to watch my birds and can tell a capable rooster from a not so capable one.
Restricting feed. I didn't only limit the amount but also gave them nothing but mixed grains, which works out to be about 11 to 12% protein in the mix I bought. This to cover their caloric needs. I kept them hungry though and they foraged quite well for extra protein. Less protein means less growth and less meat, that's why bodybuilders crave protein so much. ;D
I did, however, still end up with big and heavy birds. The bigger one probably had too big a chest to do a proper 'deed'.
The reason I put layer eggs in with the brahma eggs was because I had the space in the incubator and to see if anything would hatch. All the layer eggs hatched and none of the brahma's did.
I'm happy with my cross so far, but I'm only at the beginning. My first F2 batch has matured and, except for one hen, they got eaten already. I had a couple more F2 batches that are growing now and the next generation is in the incubator.
Wether it's worth it or not, is another question. They do not grow nearly as fast and big as the cornishX, but the hens lay very well and very big (70 - 80 grams) eggs for now. The F2 hen I kept lays less and very small eggs (50 grams) compared to the F1 hens. I'm not using her for breeding and am hoping her younger sisters will do better when they start laying soon.
One reason I'm happy doing this is that chickens are harder and harder to come by. We used to have several weekly markets where you could buy whatever in small livestock. Those days are over. It was very easy going to market, buy 10 meat birds, grow them and start over again. It's an expedition now to find meat birds at times.
At least, if this goes well, I'll end up with a bird that grows reasonably fast, lays well and has a fair amount of meat on the bones. And one that I can sustain without being dependent on unreliable supply.
Why not go for an established dual-purpose breed? Well, I ended up here by coincidence so might as well have a look where the road leads to. Also, chickens have become very popular around here, everybody is breeding them and unfortunately this shows in the quality (no judgement here, the only way to learn is through hands-on practice). The price charged for bad quality breeders is another factor.
For instance, I've had genetic issues with my brahma's that took years to improve and sometimes still show up. Although I have strong, healthy and hardy brahma's now they are nowhere near the hardiness of the cross. And they grow so painfully slow compared to the cross.
Hopefully I can keep the good qualities in the cross while improving on the not so good ones.
I'm planning to mostly do Ranger x Ranger the first few generations for that reason, and try to select for their better traits and cull out what doesn't fit. But I'll probably end up hatching out some layer mutts too, and anything that looks promising could go in the program. If nothing else a ranger roo would hopefully add some growth over layer hens.
