Why..

I'm double posting. Here I've done the work for you, here is the Genetic Wizard from World of Ball Pythons.

This is a good way to determine what your chances are when breeding snakes. Since you don't care what type of het you are getting, I just chose a male that is het for albinism, and a normal female (which you have). When mated, you get.... ALL NORMALS, with 50% being het for albino, meaning they are still NORMAL, but MAY produce albinos when bred together.

You can lead a horse to water, but I don't think it will do a darn bit of good. Having said that, here's a better option to illustrate your point:

Male:	Normal
Female:	Het Albino
Percent	Fraction	Traits
100%	1/1	50% Possible Het Albino

OP: The most likely reasons for her size are: 1) developing follicles, and 2) food. The first is likely because she is an adult female and environmental changes this time of year, combined with the fact that she's living with a male, tend to trigger follicle growth. The second is likely because she just ate 5 days ago - that meal hasn't worked through her system yet.
