AV Brahmas said: I can raise THREE SETS of CRX in the time it takes to raise one set of Brahma. Plus, I have eaten both and the CRX just have it hands down in the carcass grading.
I can understand how it would be economical if you are in an area where you have to feed the Brahmas all year round. In my area (which is wooded, damp and has lots of protein flying around the yard) I don't spend a lot to feed any of my heritage birds. They pretty much feed themselves.
Raising 3 sets of CRX doesn't do me much good if I am using 3 times the feed because then that would cost me 3 times the money making it really not worth it in my case. I butchered out both two weekends ago and I cut up all my birds and honestly I didn't notice much difference between the CRX and Brahma. CRX's ranged from 3 to 5 pounds dressed out, Brahmas between 3 to 5 dressed out. Both had great legs, thighs and wings, the breasts may have been a little leaner but there was still plenty of it and less fat on the Brahmas because they move around more. Plus I have to also take into account the cost of bedding which for the CRX is higher because they are just plain messy.
I think it honestly has to go down to personal preference what meat bird you choose and what goals you have.
