Hi, I have day old from a petting zoo and three 8-months old adopted from a family, so unsure about all their backgrounds. Here in SA you dont seem to get medicated feed, only "growing meal". One kind, nothing else. I do want to vaccinate and deworm my chick because they are in close contact with wild guinea fowl and francolin, and there has been outbreaks of bird flu in teh ostrich industry. Question is A) what all do I have to /should I best vaccinate for (what about Marek's, coccidiosis, bird flu, Newcastle, etc??) B) what are the products to use C) at what age and how often Remember, this is Africa, and things tend to be more dodgy, so I want to be rather safe than sorry! PLEASE HELP!!
