Sorry the broke scale thing, just got in my craw-
My less than tactful suggestion was put forth simply due to this- if you don't even know how much she weighs, how are we to give you good advice? Based on age? that's just no good- your snakie deserves better.
You seem to love your animals & breeding is a BIG step. There are folks who do breed at under 1500g but NOT me. These guys are pets first & used in projects only when I'm certain they will be okay.
