I have some Cornish X Rocks that I got from McMurray Hatchery the first week of September which makes them almost 10 weeks old. All the information and testimonials indicated that, at 10-12 weeks, I would have some real nice birds to butcher. One testimonial/review claims he is dressing out 10#s at 13 weeks. Well, I don't have an official weight but I doubt that I have any rooster that would dress out at 3# right now. Hens are much smaller and one is almost tiny. I'd like to think I'm feeding them enough. I didn't follow the recommendation strictly but was giving them free choice. Their feeder would run out at night Is this a myth or am I inept like it seems I am at everything else?
