So I have 2 female budgies but they start to act sorta aggressive to one another. Kaylee keeps like opening and closing her mouth like trying to bite the Sunshine or so and bobs her head while walking back and forth on the perch, but the Sunshine is just walking away. Plz help

Don't worry this is normal. My females do it all the time...Females are very territorial...They will have this kind of behavior, but if it becomes VERY aggressive...you can separate them.
I dont think its something to stress about. The opening of the beak is a deference or warning stance. Maybe the other is getting too near.

Here is a link to a budgie/Cockatiel's body language: http://littlefeatheredbuddies.com/info/gen-bodylanguage.html

hope this helps!

It's springtime so they might be getting hormonal. There are things you can do to reduce the hormone levels and this article tells you about them: http://www.littlefeatheredbuddies.com/i ... mones.html
