I found two dead chickens over night a few days ago. Another one was acting sick (lethargic, can't jump or fly). After I did some research I found out it could be worms. I got safeguard and have been giving my sick chicken that for three days and she's been inside my house in a crate. Shes acting less lethargic, but still can't jump or fly and isn't moving around much. Anyone have any ideas as to what it could be or if I should just wait it out? I have rhode island reds, barred rocks, and buff orpingtons. All five months and aren't laying yet.
