I haven't started breeding yet, but my plan as of now is to only breed when the female reaches 1200 grams and at least 18 months old. This is absolute minimum, though. My het Axanthic female should be able to reach that weight by winter, but at that point, she will barely be 18 months. I'm not comfortable with breeding her that early. I might breed her mid-summer, depending on her weight, but most likely, I'll be waiting another year for her.
