Oh Bigrock, nothing like opening that can of worms!
You are going to hear from a chorus of members here, extolling the virtues of the dual purpose or heritage breeds. IT sounds something like this : I fed my extra rooster for 8 months to get him to a lousy 5 pound carcass weight. When you factor in time and cost, that is the most expensive, and perhaps toughest bird you will ever eat. The next thing you will hear is that, well, yeah, he may be a 'little chewier' than meat birds, so you just have to know how to cook him. If you have a nuclear reactor in your back yard you can nuke him for a day or two to make him chewable. Not only do you have a bird that has taken you longer to raise, cost you more to raise, but your idea that they will all turn out to be Sunday roast birds to set on the table whole...guess again. Because he requires 'special' cooking methods.
(people are preparing their slings and arrows for me as I type this, I can feel it!
)
If you are having a Harrowsmith, Mother Earth News moment and feel the need to suffer a little for your food, hey, knock yourself out. Raise these 'other' birds.
But, if you want to raise birds once a year, for a few weeks and put 5, 6or 7 pound carcasses in the freezer, meat birds are the way to go. Give them a short, happy life then off with their heads! They are the type of bird to serve whole and carve at the table for Sunday dinner with the folks.
And about genetic weirdness, this is utterly false with meat birds. When you cross a German Shepherd with a Border Collie, do you have dogs that are genetic mutants? No. You have dogs. Mixed breed dogs, but 100% pure dog genetics. A meat bird is 100% pure chicken. It has just been crossed and re-crossed with specially selected chickens to get specially selected results. But there has been no splicing in of whale or gorilla genetics. There is a UNIVERSE of difference between selective breeding within a species and adding some genetic material from a different species! So if anyone tells you a meat bird has been genetically altered, they are horribly uninformed. Laugh at them.
Do meat birds have problems? Yes. Is that the debate here? No. Do they outperform dual purpose/heritage birds? Absolutely. Are they genetically altered? No. Are dual purpose/heritage bad eating? Not according to CynthiaM and others. According to me, they are more work than it's worth for a chicken dinner. But that is just MY philosophy. I want to raise them quick, know what the outcome will be, and be done with it. If you are interested in a different chicken experience, then you might want to consider dual/heritage.
Okanagan Hatchery in Armstrong sells day old meat birds year round.
