Although it seems kinda unlikely, maybe she's an introvert? A chickrovert?
Seriously, I understand your concern and I'd be having the same thoughts if she were my bird.
I've just mucked out the big coop. It has a heavy mesh floor, so when I put fresh litter in there I always make it quite deep so it's comfy for the chooks. When it begins to turn unpleasant I take it all out and put fresh litter in. So, while it's deep litter, it's not the deep litter method. Anyway, I was very popular with Sandy who came in while I was working and got in the way *cough* I mean, had a lovely time bug hunting among the piles of litter (that I'd only just raked up). Hahaha, I must admit she did a great job on pest extermination.
