Can you breed her? Sure you can how many eggs will you get? Probably 4 to 6.
What I would do is start feeding heavy now and start pairing her in a month or two, so it would give her extra time to put on extra weight.
Personally I like to breed big girls, to me the bigger the better but that's my personal preference.
Now there are smaller animals that I am preparing to pair as well however given their age and size I doubt they will get much larger therefore they will breed at their current wait.
From 1500 grams females I have had 4 and 6 eggs.
