I have been worried though. A few of them are doing that stretching and opening there mouth. I am worried about Gape worms. Should I treat for it or just watch them? They don't act sick they do shake their heads too. Researched alot last night and really don't know what to do. None of them have been wormed. But Wazine doesn't treat gape worms. What should I do ? I don't think I can stick Qtip down its mouth or even see in its mouth. Any advice. Some things I read said that is not real common especially in chicks if they have been in pens not on the ground. Please advise me.
