What gender is my little friend here?

[Sv3Nq8]

Hi, this is my friend Ruby and I've had it for around a year now, and the dumb me never bothered to ask or question it's gender. But now that i brought a new friend home (a male) i wanted to make sure this is indeed a female so i can breed them. Here is some few Pictures of it and if you need more context/information's let me know. Also if somebody could tell me if it's ready to breed and it's estimate age i would very much appreciate it.

Thank You <3

She is certainly a female, no doubt about it
And yes, she would be well and truly ready to breed

I would not be sure about a female, try to wait some time, please.

Thank you for the advice, yeah i've posted about it on Facebook and people are saying Male others Females i'm not sure either. Can the behavior tell the gender? it's REALLY LOUD instead of singing and it bites really hard.

Budgies reach sexual maturity at 6 months of age, and you have had her for over a year and obviously she would have matured by now
It is a definate female no doubt about it, and I have bred a lot of budgies in the past so I know
