Hi all. I came back from a 5 day family vacation to a chicken with a very poopy bum. I put apple cider vinegar in the chickens water. It's been a few days and she has worms in her poop now and she really isn't feeling well. What can I do to treat this quickly? She is about 2 to 3 years old. She was kinda sickly before I left but I thought she has sour crop because when I would pick her up she would have liquid coming out of her mouth and it smelled. so I vomited her three morning. The people watching the chickens Sid she went to eat right away in the mornings with the other chickens. So I figured she got better.
