She's likely still building. This is a good sign though as she is seeking the cool side while the follicles are developing. It takes a ton of patience because things just don't happen quickly. Think 6 months from first pairing to eggs. We started pairing a female in September and she had her pre-lay shed last night, so we are still roughly a month from eggs. Just keep an eye on her and the next sign should be her starting to brighten up (glow) as she moves towards ovulation. Best of luck.
