What in the world is this? I have never seen anything like what's on the yoke of this chicken egg! I know that on Mother's Day 2016 while visiting me, my daughter, son-in-law and I was shocked to look as one of my guineas roosters mounted and appeared to inseminate one of my chicken hens. While not knowing which hen laid this egg I collected about 4 days after the Mother's Day incident, this is what I found when I crack the egg to use. Pic is not great, sorry, but it was somewhat gritty, wet powdery in texture. And no, I didn't use it! Anyone know what this thing is? Thanks!
