Hello and welcome to the forums,
Minnow is beautiful and is definitely, without a doubt, a female budgie
Behavior is not a good indicator of gender as females can become aggressive and hormonal and try to mount/harass other budgies regardless of gender. It seems that Minnow was bullying your other female quite frequently due to increased hormones. She is also definitely not too old to tell her gender for sure, as she has her irises and has had her first moult, indicating she is an adult budgie. She looks at least 7-8 weeks in the photo you posted; additionally budgies four weeks old are still too young to leave the nest. In the current photo she looks at least 8 months old which would be right in line with you getting her when she was at the very earliest 7-8 weeks old. Around 8-9 months budgies have generally had their first moult and show mostly adult plumage. Of course, there are exceptions to this, but your Minnow seems right in line with the typical milestones.
Additionally, blue around the vent is normal for many green series budgies. There are two cases in which it can be obvious; green budgies that are split to blue often have blue around their vents and green budgies with a violet factor also show bluish coloring around the vent as well. As I don't see any traces of violet on her (which usually can be seen around the ears) I would say she's split to blue. As she gets older the bluishness may fade, it does in some budgies.
Meanwhile, you've come to the best place to learn even more about the best of budgie care practices. Please be sure to read through the forums' many budgie articles and "stickies" on the forums to ensure you're up to date on the best of budgie care practices. If you have any questions after doing so, please be sure to ask as we'd love to help.
Is Minnow your only budgie now? Is she aggressive towards you or just other budgies?
We hope to hear more updates soon!
Best wishes 👋
