Help!!

I have a girl(bria) who is about 1400 grams and I'm not really sure of her age because we bought her from a pet store and they weren't really sure...I have a 100% pied male who is about 620 grams and I've never tried to breed my snakes before, is there a certain weight I should have bria at before I breed her? She eats a large rat each week, so feeding isnt a problem.
Also, when is the best breeding time? I've heard that fall and others I have heard winter. Please help! I want healthy babies!

I like my females to be 1500g+ and 2.5-3 years old minimum. Most people start breeding around Nov-Dec. Others breed year round.

Here's some more helpful info:

Should I be worried if my girl is way bigger then my male? How Do i know if they locked together? When will i know if she is ovulating?
AHHHHHH i have so many questions!

Nope...People breed 3000g+ girls with 600-700g males.

The link I posted in my post below will have most if not all the answers you have about breeding.

Thanks!
