While I absolutely believe it's imperative to provide the females with optimal conditions for egg laying, they do not "scatter" their eggs when provided with less than ideal conditions.
99% of females become almost "stoned" when laying, as anybody who has bred hogs has witnessed, and they lay all their eggs in one place.
I only had one female "scatter" when I accidentally disturbed her and she is a nutjob at the best of times, constantly striking at every meal.
She also happened to be in a 19 gallon tub with 10" of substrate.

She still provided me with 20 "abortions".

That brings me to my second point:

"Abortion" is a ridiculous choice of words.
When I began breeding, I didn't provide females with suitable conditions for laying and it was evident in that some females - (less than 30%) - would pace before laying. However, they almost all went on to lay, without "scattering" and 95% plus of those "abortions" hatched.

I don't want to be misinterpreted, like I said, I absolutely believe we should do our utmost as responsible breeders to provide females with optimal conditions for laying.

I just want to correct certain non-empirical claims and exaggerations.
