Recently like within a month one hen got ill not eating runny poop lethargic so treated the entire flock for coccidosis. Complete 5 day round of treatment. Then last week one hen dumped a large ball of worms in her poop. So dewormer the flock a week ago. Now I have an unknown age black astro who didn't roost last night I found her outside the coop with a large puddle of yellow poop. She has a squishy crop when I picked her up she vomited watery stuff. Won't eat. But is walking around I felt her abdomin no feelings of eggs vent is clear no smell from head face or mouth. Looked in mouth everything looks good. Any suggestions is appreciated. Also eyes and nose clear no mites or lice. Breathing is good also not acting herself moving slowly
