Our local feed store has Partridge Rock chicks available, and I'm considering getting two of them. I can't find too much about this breed online so I'm hoping some BYC members who have owned Partridge Rocks can tell me what they're like. Do you think they would make good chickens for a city, backyard flock? Do they lay well? How soon do they start laying? And last, at what age can you usually tell whether they're pullets or cockerels? Thank you!
