Internet, I love you. So here is a bit more information on taste and color:
Taste Some chickens, particularly ones that lay brown eggs, have a gene that converts fatty acids into compounds that can smell or taste fishy. If these hens are fed a food, such as fish meal or anything else that increases the Omega-3 fatty acids, the more prone the eggs are to this. It doesn’t mean that they are spoiled.
Color In foods, canthaxanthin is used as food coloring and is added to animal feed to improve the color of chicken skins, egg yolks, salmon, and trout. Source
@Bellatrix I would never throw an egg at you, unless we were playing Egg Toss. The freshness of an egg does come into play on how well it peels if hard-boiled. The fresher they are, the harder it is to peel.
@uberbatman I’m fairly sure that out of all of the eggs I’ve purchased in the UK, the only ones that have the fishy factor come from our neighborhood shop. Maybe the shop owner only uses one source for eggs, and that person feeds their chickens fish meal or something else high in Omega-3. All of them though, no matter where purchased, have the bright orange yolk.
@Sunny2 What type of fish eggs have you tried? I have only had caviar, and I just assumed that the salty flavor was added. Mom used to occasionally fry Shad Roe for breakfast, but I never touched it.
