Advice on new hen

[sydney]

Question from my mum..

just want to ask 4 advise please my new budgies i brought couple of days ago are a breeding pair. males fine but im worried about the female wen she sits on the perch her back end keeps going up and down constantly i just need to know why she is doing it ty

I told her she has an egg coming but she's getting worried. Bird looks healthy has an egg bum and not fluffed up.

I don't know how long are they in to breeding but it can be egg. Most hens do tail bobbing before laying egg.

She can also be stressed because of the move.

Or it just be that she is getting in to mating posture.

She's like it all the time. But my mums still goin on about it I'm debating wether to pick the budgie up and see if I can feel the egg
