My kids threw in some leftover avocado tonight. They ate some of the peels. I didn't realize they had thrown it in until later, and they have pecked at them and eaten some of the peels. Is this going to hurt my chickens? I had no idea that avocado was on the "no" list until I looked it up tonight and now I'm afraid my poor chickens are going to get sick or die because I didn't get the peels out until after they had pecked at them a good while.
