Many of my bieles had speckled eggs. The color starts out pretty dark & fades as the season progresses. The speckles should stay but main color will lighten.The breeder told me they have brown eggs and sometimes they can be speckled, I am so happy I have a speckler!!
Your girl made a pretty big egg. The size will increase, so you may have trouble closing up the egg carton. LOL (It's a great problem to have!) Congrats!
