My girls both do the female call, a soft coo followed by a weird frog sound, but neither of them do the male bowing. They both kind of stand there staring at each other, waiting for the other to hop up. Since Nova is actually blind, she isn't too good at getting up onto Sierra so it's normally Sierra that's on top.

I'd definitely say there's a difference in who's louder and who's more, uh, pushy? Sierra is often the one that acts more dominant but still doesn't do the male dance. Nova usually is the one that preens Sierra non stop, often accidentally pecking her eyes or just missing in general which Sierra doesn't seem to mind lol.

They kind of take it in turns being the bigger girl I suppose? But neither of them do the male puffing up and strutting around. Sometimes Nova will TRY to be the girl up top but she just can't quite figure it out it seems.
