I'm no scientist (obviously) I rec'd my valbazen for the worm problem, I don't understand cc's. It says on bottle: Mix 8cc of water to 1cc of valbazen, shake and give 2cc to each chicken. Can someone give me measurements I can understand? It's just a bottle of liquid with no syringe or anything. I tried looking it up - no luck, also it says I can give it to them again after 10 days. But I'd also like to know - after initial medication is given, how often do you do this as a preventative? Thanks for any replies.
