Ummmmm, nnnnoooooo.... Didnt anyone tell you only every other egg will be fertile?
Sorry, I was just kidding.... Fertilized eggs taste the same- we eat them all the time. Honestly I was kinda grossed out too....but when your hungry at 2 am, and all ya have is fertilized eggs, they taste REAL good!!
If your roo is with your hens all the time, chances are most the eggs will be fertile, not all, depending on alot of factors, fertility, age of birds, etc. But really, its not a big deal at all. Some people even prefer to eat fertilized eggs. I just told myself 'Eh, this is probably not one of the fertile ones' and I got over it.
If you just cant stand the idea, get rid of the roo, wait about 2 weeks, and you wont have any problems with fertilized eggs.
