courtship (new cock bird)

[babygirl]

I got a new pair today. a blue cock 3yrs old and a grey hen (number 2) also 3yrs. put them in my larger aviary with a few other birds one being another grey hen (number 1).
After about 2 hours I seen the number one grey hen on the perch checking out the new blue cock bird. she is normally a vocal hen calling out and screeching the house down (well aviary) the but keeps to herself. She walks up to the blue cock bird slowly and just touches her beak with his. like a soft nudge. than takes a few steps back. He seems a tad baffled by what she is doing or distracted by all the singing going on with all the other birds.
Is this her way of telling him she thinks he is alright ???
