The whole chickens that I purchase in the store are normally about 3-4 lbs. It sounds as if you all end up with a heavier chicken after slaughter. So, I was curious how the different breeds of chicken that you all raise compare in weight after you slaughter them. So, How heavy on average are your meat chickens and please include which breed you use, Cornishes, JM Hatchery birds, or what breed of dual purpose? I am still deciding what would be best for my family.
