I kind of agree that larger snakes yield bigger clutch of eggs. I was on my first season breeding ball too. Got 2 pastels female and both are virgins but over 2 years old.

The 1800g gave me 9 eggs with great odd... 3 superpastels, 5 pastels and 1 normal...

The 1300g gave me only 4 eggs (large eggs).. 2 bumblebee and 2 pastels...
