They might be, it just means that they will be fertile eggs with a rooster in with them. Some people don't like fertile eggs just because on occasion you will find blood in the eggs, when I find eggs with blood in them I just cook them up and eat them, it doesn't seem to affect the taste, it just freaks some people out to find blood in the eggs. Of course I spent part of my childhood on a small farm so I am used to seeing blood in the eggs on occasion.If have a rooster with my hens will their eggs be bloody? I want to have eggs to eat...but I have heard having a rooster will help them lay better.
