This breed is the mainstay of our free-range homestead flock. These birds forage very well for their own feed, with strong feet and legs. They are alert but calm, reasonably quiet at laying time, and dependably lay good-sized eggs year round (our flock is on a 15 hour light regime to maintain production). Most hens accomplished their molt with great speed, going practically bald before rapidly replacing feathers and returning to production. We have had very few predator problems with these birds, as their color is inconspicuous, and they are alert. Productive life was very good, with most lasting a full 2.5 years before production started to slack off, with some lasting to the 3.5 year mark. We actually still have one hen in production from our first batch---she's 4! These girls were good about laying in nest boxes, and did not have issues with weak shells. It was rare for one to rebel and take the trees rather than their roost poles. Carcasses were average for yard chickens, with time to slaughter weight being about the same as other purebred yard birds (crossbreds are a much better choice for meat production IMO).
None of the RIR's ever went broody.
All RIR roosters that we tried to keep for breeders turned very mean and nasty before reaching 18 mos.
Overall, this breed is well worth adding to a homestead flock.
