Not a chance. The Silkies and the hen that laid the green egg live in 2 different pens. lol And these were all eggs I had marked. All even collected around the same time. A day or two difference. I put the little green egg is in an incubator last night. It seemed like it was getting a little cold under the hens. The girls are so busy tending to their chicks now that the egg isn't getting proper care, I don't think. It zipped last night and rolled itself from one end of the incubator to the other over night!
