Donrae- seriously? Didn't know. I honestly thought there was hormone usage as well as medication given to keep them from dying (because their lungs & hearts are too small for body weight). Thanks for input.
Often production birds are medicated with antibiotic due to cramped conditions, I can't speak for hormones. The GMO (Genetically Modified Organisms) is usually fed to them via grain. GMO grain isn't as healthy as non-GMO grain but GMO grain is cheeper and we are what we eat; so if we eat a healthier bird then we, ourselves, will be healthier.
You don't have to do an all or none approach re: meat birds vs. dual purpose birds. You could perhaps get a few of each. When I start some new chicks this spring, I plan to add some meat birds to the mix, leaning towards Freedom Rangers or a similar breed. And if you plan to harvest some birds for meat, it would be just as easy to order straight run instead of pullets. Hatching is always fun too.
Lazy Gardner, that's kind of what I was thinking. I know I like heritage breeds, like RIR and Orpington's (which we have), and the meat birds are intriguing because of their rapid weight gain. But, I was a little worried about the meat birds (like Cornish Rocks) due to breathing problems. That's why I was comparing. Also, read that Cornish Rocks lacked in flavor. Any input? Thanks for your help.
