Chickens from hatcheries have just as much chance to go broody. It's natural for them. If I want a chicken or duck to go broody I either leave them a few eggs for a few days or put out some fakes. I remember Barred rocks and brahmas being the best brooders when I had them years ago. They'd try several times a year if we left an egg in the coop more than one day.
Great minds think alike..
