I wouldn't argue with any of that Sean. It is in part what I set out to prove. I've often read some instincts have been irrevocably bred out of certain breeds of chicken. I believe it is all about how you keep them and my experiences here seem to show that even Marans, which are not noted for broodiness will still go broody under the right circumstances.I think it has more to do with the way you keep your chickens, Shad
Over here their more incline to raise them for egg layers not rearing young, so the instinct to reproduce, go broody, has been bred out of them.
Yours are basically on their own, i mean you do look after them and all but keep them locked up in an enclosure their whole life....they have regressed back to their natural instinct to reproduce.
