My one year old black australop hen, Luna, came to me from an FFA club along with 3 others in May. They were quarantined for 30 days, then introduced to my existing flock of 2. She laid eggs consistently for a couple of weeks then stopped (I attributed this to the heat in Phoenix). About 6 weeks ago Luna began to have very watery droppings that had high urates, so it looked pretty white. I noticed around the same time that another hen had so evidence of tape worms, so I treated the whole flock with Zimecterin Gold, at the recommended dosage (pea sized). A week after worming I took Luna into the avian vet, he said he thinks she has Ulcerative Enteritis. He said not treatable and basically I will likely loose my flock to it. Although the diagnosis was a guess, because no tests were ran. I did a little research of my own and found the suggestion that Ulcerative Enteritis has had success being treated with Tetracycline Antibiotics, so I gave that a try and treated the flock with the 1 tablespoon per gallon of distilled water for 8 days. Fast forward 4 more weeks, Luna is still alive. Her symptoms include low appetite, she recently began to eat a little breakfast on her own, although she grazes on grass all day. She is very under weight. Drinks water just fine. Droppings range from loose with a just higher than normal ratio of white urates to basically solid water. They used to look pretty slimy to me. NEW symptom! Yesterday I caught a glimpse of her sticking her head between her legs and walking backward for a few steps. She did it again this morning, but this time she flipped herself over on her back then quickly got up. Also should mention that she is in the middle of her molt and not doing a good job growing feathers back (because she's not getting enough food I think). Here's what I've been doing for the past week: Colloidal Silver in their water and I occasionally give Luna 4 CCs of Nutri-drench by oral syringe a couple times a week. I also put them all on feather boost food I picked up at the feed store, so it has a higher protein content than layer. No other chickens are showing signs of any illness, with the exception of one bantam who is on the tail end of a foul pox infection (dry pox, minor case). Any advice? I've had terrible luck keeping chickens despite deeply caring and trying. I do everything and more- high quality organic feed, occasional treats (mealworms veggies), I grow them sprouts and let them free range all day. Take them to the vet when they are sick (hundreds of dollars in the past 2 years). I've been to three vets that treat chickens and haven't had any success. Thank you to anyone taking the time to read this and help.
