Awesome! Yes she’s a femaleYes! The one on the right is definitely a pearl. If you know for sure it's a female, it will keep those markings (pearls). If it's a male, as it gets old it will molt most of its coloring now and look like the normal grey on the left.
she’s a little over 2 yearsAbout how old is she? As she goes through a few feather molts her head area may get a little darker but unlike the males, she will keep her pearls.
