I raise some Brahmas. Not pacifically for meat, but meat and eggs. We also have other types or variety of chickens.
Brahmas are very easy going, tough, descent egg layers (we have the white brahma), dont deal with the broodiness like the austrolorps. The down side I see is they are very slow growing.
We here hatch our own eggs and so we have some mixed varieties, but the Brahma roosters are the breeder.
Our chickens here is a hobby, we sell some eggs, sell some chickens, chicks and butcher some chickens. Our hobby is not a break even deal, but with what we sell and use it is not real expensive. Summer time about pays for itself.
Brahmas were used as a meat bird years ago, 1850 early 1900. The hybrids came in and took over. Years ago from a article I read Brahma roosters could become quite large.16 to 18 pounds. The size over the years has kinda been bread out of them.
Seems to me I read Brahma can get quite large at first in growth, but takes time to fill in the meat. In other words they build the frame then fill it in.
We butcher about 20 birds a year and I do not keep records.
Now if I was to raise just some chickens just for meat only, I would buy some rangers and raise them, which I have before.
Have had brahmas for 3 years now, though they grow slow as compared to other birds the other attributes as said before. I live Wisconsin, they are a tough bird and calm docile. The roosters (2 of them) do not chase my wife and daughter around trying to attack them. That part is really important. That is part of the reason I went to brahmas. Have had some nasty roosters.
