So this egg came from one of the hens (RIR) that I purchased yesterday from a local hobby farmer. Both the hens are about 1.5 years old, so this egg is old news to them. My very first chicken egg... Now I have a question... The hens I bought were kept with a rooster. If the egg is fertile, I want to try and hatch it. If not, then I'll store it for eating. Is there any way to know today if the egg is fertile, or do I have to wait a few days before 'candling' to see?
