Why do we say "per egg" instead of "per clutch"

[rabernet]

So technically at this point, you only have a 1 in 11 shot of producing 50/50. I think that's a 9% chance of hitting the 50/50 split exactly.

DING, DING, DING........winner, winner, chicken dinner! That's EXACTLY why it's far more accurate to explain that the odds are PER EGG, not per clutch.
