Help! Vet just prescribed 0.5 ml of Nolvasan solution to my Bantam Roosters Drinking water! Is this ok? I've done research and can only find references to it being used as a disinfectant and lots of warnings! History: since Jan 1 we have been treating what looks like a respiratory illness. Ruth the Rooster-yes kids named him as a lil chick and the name just stuck- was treated for parasites with Ivermectin and is on week three of a broad spectrum antibiotic (Doxicycline) by injection, weekly injections of saline fluid for Hydration and weekly vitamin injections. He is eating and drinking more yet still significantly under weight and only seems to make progress with intense consistent effort. He also seems to miss many attempts at grabbing food-looks like depth perception is off although he appears to see movement from both eyes. Most recently vet indicated lots of yeast in stool sample and sent home the Nolvasan to treat. Could this be a mistake? Thanks so much for any advice!
