I've been breeding budgies for two years now...the one in the top pic looks like a definite female and the other one looks like a Recessive pied budgie so when it grows up it will not have the normal blue cere (nose) that males have. It will be pink if it is a male and brown if it is a female when older. But right now looks to me that it is also a female not too sure about that one.. Hope i have helped!
