Being a 2013, it would put her at just about 1.5-2 years old for the 2015-2016 season (assuming she was born early in the year). It's POSSIBLE she could make it, but continue to feed her weekly and don't push too much or too large food on her.
If she makes it up to 1500g by that time, palpate her to check for follicles. If she has those she is ready.
