Your Jaeha is in the process of growing one of her main (biggest) tail feathers.
At the stage it is now, it should take 2 - 3 weeks for it to fully come out of the sheath and to grow more.
It only takes a few weeks for blood feathers to fully grow. The closest from the options you have placed there is 1 month.
Generally speaking and depending on the blood feathers (on the wings or tail area), it usually takes 4 - 5 weeks to grow.
The smallest will naturally take less time to grow.
The feather is protected but that doesn't mean that a potential accident can't happen. Things to watch out more during this time are night frights that can truly damage incoming blood feathers, also if your budgie is a bit more clumsy or very acrobatic, she could get into trouble.
Having the accessories arranged in the cage in order to prevent your budgie's feathers to get stuck/bent is a good way to limit the risks of an accident.
RIP sweet Tito (Summer 2008 - January 17th 2013).
You are missed and never will be forgotten.
