Oh no what happend lol

Bullet is molting. She'd lost her central tail feathers and one other. This morning she still looked decent. I walked out just now in the evening and NO TAIL!!  Stubby budgie!  HAHAHA. What happened?  Tails and wings don't fall out all at once. I think one of the other budgies or my cockatiels pulled her tail out.  She is a little jerk to them and probably deserved it.  I call her subby now and she moves funny.
