Usually i am helping others with problems. Now i have a new problem i've never encountered before. I had a few great quality chicks sent to me a couple weeks ago. I discovered worms in their poo, so i mixed in a bit of wazine17. Now i discover they may also have cocci, because of blood in their poo. Probably from the sand i use as poultry grit from the sand pile where a pool used to be. I am used to cocci treatments in chicks, it's in my soil, nothing i can do about that, but expose them at an early age to build immunity. I am wondering if using wazine17 and sumlet at the same time possible. I do not want to lose any of these expensive chicks, nor do i want to kill them by mixing meds. I would be thankful if someone will help me out with: would it be safe to use both wazine17 and sumlet at the same time. Should i wait a few days before giving sumlet?
