I've seen these "things" in my chicken's poop for quite a while now. I can see that they are not going away even though she is the only chicken I have left and we've move to a completely new state. She's a Barred Rock and I found her about a year and 1/2 ago. I have always suspected that these are eggs of a worm but I've never seen a worm in any of her droppings. She seems healthy. The whitish dots are about the size of the head of a pin, soft and squishy. If you have a suggestion or if I just need to treat her for worms, that'd be good to know. I have not done any kind of treatment because I'd hate to be without eggs for a couple of weeks. Selfish me.
