Was wondering where you’ve beenI'm chiming in rather late here, work has been crackers lately.
Mary and Janet rotate sentinel duty and I reckon it's a habit they established when they were a dynamic duo. Janet strenuously supervises roosting - on a few occasions, her supervisory antics have caused her to take a misstep and tumble off the roost! SO embarrassing for her. And these tumbles mean Mary has taken up more status, along with her new feathers and laying. Janet is 2nd bird now.
Sandy can dream, but with her shortened beak, she'll always be third bird.
I pat squatters along the back too! And because mine are none too tame, I take the opportunity to feel their keel and lift their hackles to examine the roots for mites and lice. Only trouble is, Mary doesn't squat so I have no real idea about her keel
... and would she be... Big Bird 
.... so today she got extra hugs for doing such a great job on that first egg!
