You know...it's funny you asked that cause I always thought the same thing Poulets De Cajun said. But then I bought eggs from a BYCer a few months ago and they came with sharpie marker...I was really worried and even asked the person I bought the eggs from if it was okay and she said she does it all the time. So, I hesitantly set them. Anyhow, it was the best hatch I ever had from shipped eggs!!! 11 chicks!!!
All are healthy with no weird side effects!!! Do I use a sharpie...no. I still get worried I will lessen my fertility rate! lol I know...I'm hopeless!!!
