How long do Indian Runners take to hatch their eggs?

[Awaytome]

I've had two Runners go broody. Both were six years old at the time. Only one successfully hatched her clutch and she hatched a second clutch the next year. One of her daughters also seems to be a broody. One of the reasons I wanted Runners was because they don't go broody. Oh well....

The offspring of my runner hen are grown now and are as broody as their mother. Not sure if it's the "water" or what but my Pekins go broody too.
