Hi I'm not sure whats in my brown eggs they are layed by Barred Rocks the Polish chicken and the Auracanas are fine. When I crack them open thy have a small biege square thing inside, though sometimes it has a redish tinge it doesn't look like a blood spot up close though. Can anyone help ? Oh and the Auracanas eggs have dots on the outer shell, this one was in the shape of a 2. Can worms show up in eggs and is that what it might be? Need help don't want to eat them till I know.
