Thank you for all your replies. Some I wasn't expecting and got a good laugh. I should have thought about it carefully before I used the word "natural" and "organic". IT DOES MEAN DIFFERENT THING TO DIFFERENT PEOPLE!
The reason my partner was bent out of shape was the fact that they grow so fast. To her, it's just another Frankenfood! She knows its no more dangerous or safer than a heritage breed. It's not like eating Twinkies. She'll eat it without hesitation BUT, and this is where we got in a big conversation: is it natural to breed them so that they can grow so fast or is it natural that they grow so big to have heart failures and broken leg or is it natural that they grow so big (what about Jersey Giants some want to chime in).
Our brahmas are not slow in moving but in/were slow growing so they would be a lousy choice for selling as meat bird. Even as a layers they are not the greatest but they are okay. We are willing to accept it.
I especially liked reply from Fred's Hen because it was closest to what we were thinking. So thank you. And everyone else who gave me a perspective I wasn't thinking about so thank you.
and yes our brahma's are dual purpose. We eat the eggs and the meat goes to our dog and cats. Stewing hen, our dog and cats think its much better than us.
