pictures of two of my meat birds. these are obviously girls. the boys were larger. 13 weeks? I'd have to check my notebook to be exact but they're about that.
the first one has been on free range since she was about five weeks and I could start to tell which were boys and which girls. the second has been in a tractor. she's only very very slightly larger. They're about the size of my EE hen, although stockier and much broader through the breast. I don't know if I did something wrong raising them?? I'll be weighing the carcasses today. I have to borrow my mom's scale. mine suffered an accident when a toddler attempted to take it off a counter.
My one pullet CX was about 2lbs lighter at 13 weeks than the boy I did at 10 weeks. They just are smaller. Although her table weight was still a nice 7-8lbs. I did notice though the CX start getting fat deposits after 10 weeks. She had some, small, but she had some. The boys had none at all.
