Mortality

[chasing ducks]

My indian runner duck eggs have been in the incubator 12 days now. I tossed one yesterday as it showed absolutely no life, no veining, nothing. The other 11 all have swimming embryos, anybody have any idea what my chances are of hatching all 11? It's my first time trying this, I'm monitoring the temp and humidity closely, but am just not sure what the mortality rate is once an embryo is seen.

100% impossible to give you an accurate answer. No reason a majority shouldn't make it if the variables stay within the controlled ranges, but it's really a crapshoot.
