Hi Everyone, Does anyone out there know what to give ducks that will kill gape worms and all the other worms they get too? Also where can I get the medicine...? How much to use? What about my babies? Also can this wormer be given to chickens? All of my critters get to free roam during the day. So I figure everyone is infected and if they aren't I still want to treat them all! Thanks for all the help I'm hoping to get. Because I haven't had any real luck on my own trying to find something!
