Make A Hen Go Broody?

[GuineaLady93]

I was thinking about letting one of my hens sit some guinea eggs for me is this a good idea and will she do it? We have just been collecting her eggs everyday, so how can I make her go broody?? Can I just leave the egg she will lay in the morning and add about 15 or 20 guinea eggs???
Thanks,
Ashley
