I raised a set of brown broilers this time for killing. They are decent size at 11 weeks, but nothing like the cornish rock crosses. They are much healthier birds. They do not eat as much as the crosses. I will kill them at 12 or 13 weeks and see what they weigh out. They are beautiful birds. I guess it depends on what you are after. I am pretty happy with them so far. I was pretty happy with the crosses as well.
