Breeding budgies

[Queen]

so this year we decided to let our lovely budgies breed
they have been so great all lovey dovey
This morning when I went to feed out the female budgie had attacked her partner i dont know why
But then they are all happy again
I don't quite understand this behavior

I thought so why do they get so grumpy
