This one will be of interest to professor will i should think!!! 
Over the last few years, I have been keeping records of most happenings in my collection, but due to selling eggs etc, I have never been able to take accurate data on percentage egg development of the crested and marbled newts. However the data i have obtained (which i shall post asap) seems to show no correlation between egg numbers and percentage survival.
Has anyone else observed this with theirs?
I have spoken to other crested newt breeders about this situation and they have told me that it doesn't always appear to be the case in captivity that 50% of all these species eggs die due to a chromosome anomaly at the tail bud stage.
I have some rather delusional ideas about why (if true) this could be the case.
Any comments would be appreciated.
