One for sorrow

...Two for joy,
Three for a girl,
Four for a boy,
Five for silver,
Six for gold,
Seven for a secret never to be told,
Eight for a wish,
Nine for a kiss,
Ten a surprise you should be careful not to miss,
Eleven for health,
Twelve for wealth,
Thirteen beware it's the devil himself.

Any more than that call an exorcist. Or the RSPB.
