I was hoping someone could give me some clues to what makes an egg a good candidate for the incubator. My second batch for this spring hatched this weekend. I know which eggs come from which hens, and was disappointed to see that none of my Golden Sexlinks, Hamburg, or Wyandotte's hatched. When I candled them early in the incubation, I noticed that the Sexlinks eggs were very porous.
There are 12 hens to 1 rooster, so shouldn't be any problems there. Most of the hens are 1 year old, with the exception of the Golden Sexlink, Hamburg, and Rhode Island Red(3-4 of the Rhode Island Red babies hatched!).
Are there physical indicators of fertility that I can take note of before putting the eggs in the incubator? If they aren't fertile, I'd be happier eating them :)
