She's been like this for about a month now.
Nope, her feet are all good. The vet gave her a thorough physical check (to her horror!), including under her feet, her legs, took samples of her feathers to trace any signs of mites. No signs of any scabs, cuts, sores.... nothing. She's completely clean inside and out of any parasites and sores. She's almost finished her antibiotics now too, and there's no change in her behaviour, so the "imbalance of bacteria" in her poop must not have been too serious. She found herself a dirt hole to lie in this morning in the corner of the garden so I suspect she will stay there for most of the day.
I know, I cannot figure out what could be up with her at all!!! Haha! Neither can the vet. So so weird. I lost a chicken last year to egg peritonitis and it was very obvious she was sick. And I had a chicken a few months ago with giardia and she had a scratch on her foot which was bothering her, and again, very obvious she was not well (she's ok now though), but this one doesn't act sick at all. Just acting lazy.
