From what I have experienced, Plymouth rock and RIR.
My RIR is 2 1/2 and has been broody once before, I think it depends on the individual (not just how they're bred)
My PR is 1 and has hatched out a batch of chicks and is a great mum. She's a good mum, attacks the dogs, pecks other hens if they get too close, but still lets me mess with the chicks.
Both hen's lay almost every day when not broody.
