You will catch her, if necessary, when the light is dim with no problem. I remember once Emily would come so I turned off all light, used the light from my cell phone to find her, offered her a perch, she jumped on, and I put her to bed.
Have you tried putting a perch near her to see if she will hop on????
Try not to get anxious...they can sense this...
Have you tried leaving the room? maybe she will investigate if you're not watching.
I'll be watching for an update!!!
