I know this sounds ridiculous and foolish and like I don't pay attention to my animals, but I just found out that my mother and sister who smoke throw their cigarette butts on the ground. I don't know if my ducks, geese or chickens have been eating them but it's only been recently that they've been throwing them out on the ground. I know they won't digest, but will they pass through their digestive track? I'm very very worried. Please any answers will help.
