Budgie Behaviour. Is She Expecting?

[Guardog 0]

G'day.  I'm new to the World of Budgies.  I got six two weeks ago.  I have revamped an old Cocky cage and inserted three Boxes.  Two looked quite happy with each other and I think they may have had a little liaison.  George (girl) has been interested in one of the boxes.  She has pecked at the opening and gone halfway in.  Is it the case I may be a Grand Pappy???

She is preparing and inspecting the nest but you have 6 budgies in 1 cage with 3 nest boxes? that is asking for problems i woudnt recommend that at all.
