I live in south Ga where every vet says they don't treat chickens. I have a hen about 7 months old that is in with 8 others. I removed her this morning she has been sneezing for a day and her eye became bubbly. I am treating all the chickens with Duramycin? In the water. This morning my hen was cold ( it was about 40 degrees this am) we did have a heat lamp on the pen. She was alone in the corner with her feathers poofed out. She is now coughing and has a yellow mucus in her beak. No swelling. The feather around her face are crusted and she does have an odor. I tried to get her to eat oatmeal this morning but she has not ate or drank today. She was drinking a lot yesterday. As crazy as it sounds...I gave her a breathing treatment and she really enjoyed it. She even clucked at me afterwards wanting me to come back. She has been coughing a lot more now. I have no resources in my area and will have to order anything I need to buy. Can anyone give me advice? My 5 yr old daughter is so upset and now here sits her sick hen in my livingroom. Thank you for any help!!
