I've had hatchery buff Orps. Hated them. Had them a few times from a few sources. They didn't go broody much and were mean. Hens were bullies and roosters were human aggressive. Mine were nothing like people describe.
Had English type Orps before Leghorns. Never had one go.broody.
Now when I had Marans they surprised me. Each one would go broody 2, 3 or 4 times a year and were great free range mommas. They often shared chicks too.
Hunh. I had hatchery BOs but could not tell you which hatchery. They'd lay 8 eggs in the spring then go broody, like clockwork. Could not break them for love or money. Sweet birds but useless as layers. After 3 years of this they made good soup.
