I just purchased nine Rhode Island Red hens which just started laying. So far they have been laying 8 to 9 eggs per day for the past three weeks. My question is why am I having a hard time getting the white of the egg to properly cook when making over-easy eggs. I'm 70 years old and have had many chickens in my lifetime (and have cooked my share of eggs). This is the first time that I've encountered this problem. If I cook the egg until the whites are done to my husband's liking, the yolks are hard. I've been feeding a layer mash from the same mill that I've been using for years. The girls free-range outside and also have the entire downstairs of our large barn as their coop. Are they lacking protein?
