I am new to chickens. I noticed a round rubber band like thing in one of the birds poop. It is round about 1in. It didn't stretch out or open up (yes I had on gloves) she could have gotten a rubber band from the yard. They eat anything. But I wanted to check and see if it could be something wormy. I give them Mothers Apple Cider in their water, they were vaccinated when they were hatched, I put DE in their food and bedding and feed them yogurt. They have been healthy so far and it is just one. Is it something I need to be concerned with or no? Do you know?
