Having had warrens for years and no sign of broodiness, we got an incubator ...
I now have approx 20 hens, and 20 quail all incy raised ,who behave perfectly naturally (if not more so than the ex-battery farmed warrens) Its natural instinct to dust bath, scratch for worms etc.
They are also slightly tamer, so its less stressful to e.g. clean them out, administer wormer or whatever. But they are not overly tame either.
Some are positively wild!
(We also hatched a number of cockerels who are but a memory, and a batch of quail who became ill & many died.)
This year, two of those hens have gone broody - one is in an "all girls" shed, so I ignore it and shift her, the other is currently sitting on about 8 eggs.
I'll let you know how she gets on....
I'd also like to have more ducks, and none of them show any sign of brooding.
Some of the hens are rare breeds, its a way of improving numbers & stock without the chance of mother nature killing them off, eg by cold or predators when they're small.
I'm kind of "on the fence" - If we'd have had broodies sooner, I may not have bought the incy, but then we wouldnt have the stock we have now.
It may not be "natural" (which I would prefer) but in suits certain circumstances.
