Storing eggs, how do I tell if they're bad?

[Autmizak]

so I've been collecting eggs for 4 days now. Today I got my 3rd egg from my one silkie hen who is the only hen I have that lays right now. Her eggs are fertile I believe because I have a rooster in there with her and I cracked one of hers and saw a donut shape. So if I've been storing them in my basement and watching that the temperature is between 50-65, should I see anything when canceling them or will I only see things when I candle them after they've been incubating for a week?

You would really only see things when they have been incubating for a week, its the easiest way to tell
