I have a bearded polish hen that started acting lethargic and rapidly losing weight. All the internet searches pointed to things like a stuck egg or impacted crop. I had given her warm baths, massaged her, and checked for issues with no luck. She drinks and eats when I help her, but not on her own. I was feeling very puzzled until I noticed a worm show up in her water dish tonight. It was about two centimeters long and looked like a little earthworm. A little research later pointed to gizzard worms. Anyone have experience with these? What sort of time frame do I have here? Anything I can do for her tonight? What can I purchase for her for treatment tomorrow? How can I keep this from happening to my other chickens? Right now she is quarantined with water and basic feed. I managed to get her to eat a few high calorie treats earlier today. She is very thin. Thanks in advance!
