Pros: Large Birds
Cons: more care in & out of coop
I have succesfuly raised cornish cross breed with no leg problems. We use Willard Water, remove feed at 7 pm until 8 am.
They are ready to eat in the am BUT do not sit in front of the feeder 24-7 and just eat.
I have them out side in the day, you have to make sure they do not hurt themselves when getting out of the coop. Some of the girls do not want to use the walk way they just want to hop out.
We just butchered 15 and had a couple that weighed 8 lbs, with an avg of 6.5. So I feel good about what we are doing. AND great flavored meat !


I also free range my cornish X's and can report same results as you. They are smart and good free rangers.
It was so hot here when they got to the size I wanted to butcher at so didn't. I like them larger than fryers but smaller than roasters and by the time it cooled off last fall they were all roasters. In the 8 to 10 lb range.
No leg probs and as a bonus they go broody and are as good at setting as the other chickens
cheers
No probs w/legs, have 2 cornish x hens that are 4 years old now sorta as pets I guess. Tho mostly too tough to eat but they still lay so good enuf.
No leg probs ever, they tear across the yard after a bug as well as anything else.
New BABIES 10 days away in 'bator, wyandotte layers, then every 4 days after duckies and goosies next
cheers
