They are free as long as the skin and visable fat is removed. They are cooked on a spit too which is better. All the chicken meat is free without skin and fat , not just breast. My fave bit of chicken has always been the dark underneath meat. MMmm
I recently bought one from the spit at Sainsburys. When i got it home I changed my mind so popped it in the fridge to eat cold the next day. When i came to get it out i was shocked at how much congealed fat had seeped out and a thick layer of fat on the underbelly had formed. I never get this from a chicken I roast at home.
