We have TSC and a feed store. TSC didn't have what we needed and the feed store had copper sulfate but it was the size of your average food bag. WAY too much for what we're using it for. We went to a fish store and they had a product that has 70% metronidazole and 30% excipients. It's the closest to fish zole I could find. Are excipients safe for chickens to consume?
That's true but we don't have the time it will take to ship it here. Just caught another hen in my flock with canker. Can you look at my post above and tell be if the ingredients are safe for chickens?More than likely you will need to order it online - this is what you are looking for "Metronidazole"
