elizmartin,
We have had our since late February, and during that time they have been allowed to free range a significant amount of time. Their permanent housing is an open-bottomed tractor. We have found them to be good foragers. They may not be the best we have, but when they are allowed to get out and scrounge for their own keep, it drops feed consumption by about half. The roosters tend to be on the look out quite a bit, while the hens go about their business. Given their size, I would highly recommend ranging these birds as much as possible. Hope that helps.
Best,
Brice @ SF
