Rouen roosting?

[ducks and geese]

My rouen has taken to roosting on her nesting box over the last couple of days. Is this normal? I moved them outside last week and she started her habit. Help please

Are there eggs? She could be going broody.

Or, she could be ill - hard to tell at first. Has she started lowering her head and opening her bill and giving the stink eye? Or does she seem really drowsy and lethargic.

She is lively, but her quack sounds different and higher pitched. Thanks for the possibilities, and she was laying, but she stopped for a bit.
