I have 7-8 month old pullet. She has been suffering from one or multiple upper respiratory diseases for about 6 weeks or so. I have tried via my vet, Tetracycline, Erythromycin, Lincomycin and am currently using Baytril & Metacam. The first 2-3 weeks she lost 2 lbs and wouldn't eat or drink. But after that, she has been eating and drinking and feels much better. She is still have some mouth breathing due to the fact that her nose is stuffed with yellow snot. I have been feeding her eggs and she has learned when the plate is in front of her, so she blindly pecks with success. I have also used VetRx, Garlic, Nutridrench, Electolytes, Vitamins. And the past 4 days I have put Terramycin in her eyes. Its seems the swelling is very gradually subsiding. I wondered if anyone has any ideas on what I can do next? I'm not really interested in culling, as she is a pet. Thanks in advance.
