I've been noticing recently a small brown speck (like a grain of sand) on alot of my egg yolks. What is that? Sometimes its a bit bigger....I pick up eggs daily. I've occasionally seen a blood spot but this isn't red like that and it is about the size of a piece of sand. Does anyone esle see anything like this.....I'm freezing some of my eggs right now and i'll post a picture when I get another one.
