rickerri, we got ours for the dual purpose as well and because they are supposed to be able to handle the summer heat better than most others. We were told they will also brood well. They have finally started to lay regularly, but only an egg every other day. Or else half aren't laying

But it isn't the eggs I want to eat. I plan to hatch and then hatchet if you know what I mean.
Our main laying flock is actually ducks, Khaki Campbell and Pekin x Swede (which seem to lay better than the pure Swede, but don't go broody as the Swede). I actually prefer the hardiness of the ducks, chickens are high maintenance by comparison and ducks seem more dependent on light and independent of temperature, so it is easier to keep them laying all year. They are better than chickens at foraging in winter too.
