I have 5 or 6 Buff Orpingtons so it's hard to say if it's the SAME hen every year, but I *always* have at least one BO who goes broody. I also have 2 Cream Legbars, a Gold Laced Wyandotte, a White Leghorn, and another hen (unknown mixed breed) who are all also broody... I love watching the hens raise chicks, even if I DON'T love their aggressive protectiveness... But every year I let them try to hatch chicks, I inevitably get some dead chicks who get trampled to death by hens jockeying for control of the nesting box. If I try to move the broody & eggs to a broody box, they abandon the eggs.
So I rarely let mine actually hatch eggs...
