So weird thing- last night we separated her from the other girls as a precaution, and I gave her some nutri-drench (we do this every once in a while because she's always been a sickly hen, try to keep her a little stronger), and i mixed some dried oregano, dried basil, ground cinnamon, fresh rosemary, dried thyme, pressed garlic, and Vet-Rx into her water (i read that all of those are good for respiratory)
well... this morning, she was perfectly fine, and has been all day. let her out into the yard (separate from the others) and she was exploring as usual.
is it possible that she got over it this fast???
