One of my chickens has green poop, ranging in shade from bright green to muddy green, blocking her vent. We gave her a bath to remove most of the poop, and now she's walking around slowly and is somewhat hunched over. She's also eating and drinking as usual, but her tail isn't up and she's not being as noisy as all the other chickens. We found this out in the morning. Is there anything else we can do for her?
