I was talking to my neighbor. She said that they were getting rid of their roosters. I asked if she was worried about our other neighbors. She informed me, "No, my husband has read that fertile eggs are bad for you." I was a bit taken aback as I have always read that fertile and non fertile eggs have no difference in nutrient or safety value. Has anyone heard this before? What is the reasoning behind the belief that eating fertile eggs is bad for you?
