I have seen some hatcheries advertise a slower growing cornish cross. Does anyone have any experience with these birds? Do they still have leg problems like the faster cornish X? How about some of the "medium" briolers out there? I just read the 25+ page journel on the FR. Chickens and it seems like they would be alot more expensive to feed with them going to 12 weeks rather than 8 weeks. I was just wondering if there was something that would be in the 9-10 week range that someone has had good luck with.
