She knows, you saved her life. She feels safe, special and is bonded to you as your child. She thinks she is a non-chicken. There is no mirror, except you. If she became broody, or you can trigger it by moving her to a nesting box with some 'day old fertilized eggs' in the nesting material and place her on top. Remember, she's special, so use some of her 'blanket' cut up into smallish pieces, enough so she can have the scent of it under her. If you wanted to calm her take a t-shirt you have worn enough so your scent is on it and with some painters tape etc... tape the t-shirt behind her and then tack a few nails into the tape to hold it in place. Move her during the night, when it is dark, in order for this to possibly work. You might have try this a few times. Simulate some of the stongest scents from your room and have a clock nearby, so she can't see it but hear it (simulating your heartbeat). Your t-shirt scent=safety and the ticking=your nearby.
