I ordered 25 Cornish X's from a local hatchery in early August, thinking I would start small and maybe do another batch of 25 before the end of the hatching season to really fill my freezer. This was my first experience. Well, 9 weeks later, I am shocked to figure out that those 25 chickens have put about 150 pounds of chicken in my freezer! I am thinking now that I won't be doing another batch! The smallest have butchered at 5 pounds. Most have been about 7.25-7.5 pounds, and a couple have been 8 pounders. I am happily surprised because I didn't expect to put so much meat in the freezer, having only the typical grocery store 4.5 pound bird as my previous frame of reference. I had Purina Flock Raiser available to them 24/7 with ample fresh water. I didn't let them out because it was so hot here (I'm in the California foothills) that I was concerned about them getting too far from the fresh water... I might do that part differently in the spring when it isn't a hundred degrees everyday. Anyway, thanks to those of you who help newbies. I picked up a lot of good info just lurking here as they grew.
