I noticed the other day that the white dot had changed in my eggs. I have 3 year old hens that currently lay. They are in a run with my new spring chickens, three of whom are roosters. Now, only 1 of these roosters is crowing/acting like a rooster. He is only 12 weeks old, but he has been crowing and I've seen him mounting the younger girls who are not laying since he was 7 weeks old. He is the silver EE in the second pic. Do you guys think this egg looks fertile? I would just throw some in the incubator to test but I have reached my capacity for poultry and have a hard time killing something that has already gotten started . Thanks in advance!
