Is she old enough to be sexually mature? If so, and you give her a quiet, dark place with lost of nesting material and she's had a lot of sunlight during the day, she could be trying to nest. It's a possiblity. You can try to limit her light to 10-12 hours and see if that helps. I have a maroon belly who is supposed to be female (haven't had her DNA'd but she was a rescue and the rumor is that "she" laid an egg at one time) but she's never done that to her papers. Very interesting though... It does look like a cyclone hit her cage in the shredded pic.

If you think she might be nesting, give her some extra calcium now in case she is "eggnant". It can keep females from getting egg-bound. Lack of calcium is a problem for egg-laying hens even if they aren't fertile eggs. If you want to discourage her from laying eggs, don't give her a box to nest in and take away the material she uses to nest with or keep her from getting to it with a grate between her and the papers below her. Chronic egg laying in females can sometimes happen and calcium can be a big issue then. Unless you're breeding her, it's best to discourage her from laying eggs if you can.
