Last Sunday I made waffles and eggs, and by lunchtime I was throwing up and couldn't keep anything even water down. Yesterday I made eggs and bacon and toast, and again was throwing up by lunchtime. Both times, I used the duck eggs and I have to conclude that they are just too "rich" for my system to handle by themselves. I've used them in baking and not had a problem but I won't try eating them "over easy" again!!!
