egg yoke

Help! My chicken layed an egg twice with these different spots on the yoke. Once last week and then today. Does anyone know what they are?

Hello all, I went to make my daughter some scrambled duck eggs this morning, cracked the egg open and the yoke was a thick gel consistency. The follwing 3 eggs were the same. We have been getting close to or below freezing this week, but the eggs have been sat on by our hen until we gather them...

Egg yoke greyish color We’ve been finding some eggs from our hens with yokes that are a greyish color instead of the normal bright yellow. Can you tell me why?
