I was going to mix this egg into some blue cheese crumbles for a quiche, but when I cracked it open, I noticed the hard inclusion in the yolk. I have been previously told that rooster ejaculate can calcify. Is that true; if so, does that appear to apply here? I'd just like to know for my own morbid curiosity and if one of my egg customers finds something like this one day, I'd like to have an educated response. Because eating an embryo that came out of a birds privates *can* get weirder... Thanks!
