I'm really confused on the effect of garlic on chickens. From most of the basic chicken care sources I have read, the only harm garlic can do to chickens is to flavor their eggs. I have heard some people here on BYC say that garlic helps deworming to some degree. I have been giving my hens some garlic in their kitchen scraps because of this. Yet today, I found some info that stated that garlic could cause Heinz anemia in poultry. So, can someone give me some information on what exactly the deal with garlic is? Any help would be appreciated.
