I had an abundance of eggs this summer so I froze them. I'm not really sure what I was thinking because I've read plenty of threads about scrambling them a bit and throwing in a pinch of salt - but I saw a post where she froze them with the yolk intact so that's what I did. Defrosting them - the yolk is really hard and sludgy - almost like it was medium boiled. Did I ruin these eggs? Can I use them for anything at all besides feeding back to my chickens??
