I haven't noticed worms in the poop, or any other invaders around her vent. I'll definitely post an update once she receives the medicine. Being a relative newbie, I haven't wormed them before, so I really hope that works.
I am also experiencing very similar symptoms in my chicken. In fact I have lost 2 chickens in the last 2 weeks of these symptoms and I noticed another one seemed off as of yesterday. I am anxious to hear any advice because I am concerned that it is something that is passing from chicken to chicken.![]()
So I took my chicken to the vet yesterday! The vet thinks its either a bacterial infection or perhaps a parasite. She gave her antibiotics and a de-wormer and sent her poop off to the lab. I'll get those results today! She's not herself yet, but I can keep you posted!
Her symptoms were: lethargic, not showing interest in food / drinking, not acting herself (vocally, running around, foraging). Her comb / wattle were still red and perky and she had laid an egg prior. We did have a heat wave the day these symptoms spiked, but she was brought into the house next day and given electrolytes.
Hope your chickens are doing better today!
