Most flavorful breed?

what are the best tasting breeds of chickens

Barbecue, Thai, and Cajun.

I am very fond of Australorp as an easy to keep, good foraging breed.  Dark Cornish is a good breed also.

To be honest with you, the best tasting chicken breed, is the chicken that is the healthiest.

I grew up on adairy farm and so we grew up eating the cows that were on their way to death...stressed in other words, and it was never the best tasting meat. But a person can beat that with any type of livestock. Just raise it so that all its needs are met, that will reduce stress within the animal, and when it is time to kill, do not ruin all that hard work by stressing the animal out with a drive to a slaughterhouse.

On my farm, there is no stress because they never knew what hit them, They gleefully are eating at the grain in the bucket, then bang, they are in cow, chicken, and lamb heaven.

It is not the end of the world if they go to the slaughterhouse. They have horror stories of the places, but honestly, their end is really quick there too. They get a wee bit more stress from the ride to the place, but it is not that horrendous if a person can not do the final deed themselves.

I haven't tried home-raised cornish-cross, but I've raised Freedom Rangers, and culled roosters from the egg laying flock (mix of several WYandottes and a few other breeds).  We did a side by side taste test with a culled rooster and a Freedom Ranger.  Nobody in the family could tell the difference.  The broilers were slaughtered at 10 weeks old, and the rooster at 16-18 weeks old IIRC (might have been more than 18 weeks, but definitely not less than 16).  When we did the taste test with the Freedom Ranger vs store bought chicken, the Freedom Ranger won hands down.

So, as a result, I have no intention of raising "dual purpose" chickens in order to get the meat.  There's just no particular culinary advantage for my family.  YMMV.

The most flavorful chicken that I ever ate was a black skinned/fleshed Silkie. The head chef at a local restaurant says the same thing. Problem is, that eating black colored meat is very off-putting!!!

After that, the best tasting chicken to me is one that was raised free-range only, without supplemental grains.  The difference in flavor between a free-range egg and a caged egg is astonishing. The same thing happens with the flesh. Meat that is filled with naturally occurring vitamins tastes much better to me.
