Bought these from a local and they may be fertile. They were to round out my incubator to get a full load. My eggs in the incubator are Jersey giant, Easter egger and NN hens with a Nn rooster. I used the top ten of these in the pic. Is it possible to tell what breed may be based on egg?
It’s possible to deduce what hen laid the egg but not what will come out of the egg since who knows what rooster fertilized the eggs.
But for the more common eggs like brown eggs it can get a bit harder since brown egg layers are more breeds than say the dark chocolate eggs and olive and blue.
