Chicken tail feathers?

Hey everyone, we got a few chickens about a month ago now. They are silver laced orphingtons, 6 hens and a rooster. We got them just after they started laying so they are still young.

One of the hens (light brown) seems to have little to no tail feathers, or they are pressed down constantly. They have been like this since they arrived. She is not egg bound either. We are new chicken owners so I’m wondering if we should be worried? She’s still first one to the food and pretty vocal and social so she seems fine in that regard.

Is she just the roosters favourite perhaps?😅
