I just discovered white tiny pellet sized worms wiggling in my almost 6 month old hen's poop. We clean her poop up around our yard and so forth daily and have never seen any in her poop before. How do I get rid of these safely and could they kill her and how would she have gotten these? I also have 2 small dogs and one ate part of her poop which was black and runny (which also isn't normal) the other day before I could stop her. I am concerned that maybe the dogs could get these also. Please help!
