Butchered a 6 week old x-rock on Saturday AM. Refrigerated it until Sunday PM. Cut him in half and onto the grill for 1.25 hours and then covered with mustard BBQ sauce. My wife,3 y/o son and I ate over 1/2 the bird. Here is my comparison of home-grown ~vs~ store-bought bird. The bird definitely smelled and tasted different. I think just the fact that it had a smell is different than store-bought meat. The meat was a little firmer, not tough but just firm. It looked identical to store-bought. I can best describe the taste as "meatier". It wasn't at all unsavory but it had a different taste. I would like to do a test and serve a home-grown bird to and unknowing "victim" just to see what they thought.
