In all the years we have had chickens this is the first time I have had a hen with a disease. The disease is called Trichomonis or Canker. Chickens get the disease from drinking or eating after pigeons, doves or other wild birds have used their waterers or feeders. This hen was not able to fully close her mouth so she had problems eating and drinking. She was not well and dropped weight to 3lbs and we isolated her. No store carries medicine for birds. I checked TSC, Walmart, 2 feed stores, 3 Vet offices and pet stores but not one of them carry anti parasite/antibiotic medicine for chickens or any other bird. The medicine to cure the disease is Flagyl also called (Metronidazole). This medicine can be found in aquarium fish medicine called "General Cure". It's sold online and at Petsmart. 1 box of 10 packets that treat 100 gallons of water total. We have been giving this to the chicken for 3 days and she is healing and getting better.
