Blood spots are caused by the rupture of a blood vessel during the formation of the egg. These tiny spots do not indicate a fertilized egg. If desired, the spot can be removed with the tip of a clean knife prior to cooking.
Chickadee eggs are white with small reddish-brown spots. The eggs of these cavity-nesting birds are rarely seen by most birders because the species does not usually choose artificial nest boxes.
Speckled eggs can happen if the shell gland is defective or if there are disturbances in the chicken house during the calcification process of egg formation. Too much calcium in a hen's diet also can result in speckled eggs. These eggs are still salable and speckling does not negatively affect the quality of the egg.
Deep red yolk
These yolks come from chickens that are feeding on lots of dark red pepper or anatto seeds.
Yes, it is ok. It's rare to see as less than 1% of eggs will contain a blood spot. Normally during grading these eggs will be separated, however sometimes an egg will slip through as it's harder to see blood spots in brown eggs. Blood spots are caused by the rupture of a blood vessel during the formation of the egg.
Yolk colour has no longer any relationship to quality or nutritive value. All chickens in poultry factories are fed mainly cheap, non nutritious grain, and this produces a pale or white yolk. Poultry owners had discovered 60 years ago that they can control egg yolk colour.
Simply fill a bowl with cold tap water and place your eggs in it. If they sink to the bottom and lay flat on one side, they are fresh and good to eat. A bad egg will float because of the large air cell that forms at its base. Any floating eggs should be thrown out.
If you crack it open, a fertile egg can be identified by a small white circle on the yolk, that has a 'bullseye' like shape - i.e. one small white circle, with another white ring on the outside of it. This is created by a cluster of cells that, if incubated, will hopefully develop into a baby chick.
Egg marking is a form of egg labelling that includes an egg code stamped on the egg itself. In the EU there is a producer code regulated by law since 2004. It allows consumers to distinguish free range eggs and organic farming eggs from the industrial caged hen production.
Toss any eggs with whites that appear tinted pink, green or red; this is a sign they may contain bacteria that can speed up spoilage and may put you at risk for food poisoning.
Eggs that Make a Speck-tacle of Themselves!
Bedazzling speckled eggs are a rare and special treat! And, while the dynamic duo of chickens responsible for laying these eggs on a regular basis are the Cuckoo Marans and the Welsummers , other breeds do at times lay these egg-straordinary specimens.
Since the time of the Gemara, there was a real concern that any blood spot that was found in an egg was blood created from fertilization. This would create a problem in that the entire egg would be considered an early stage chicken embryo, which would be forbidden for consumption.
You'll see blood pumping through the heart of a tiny, developing embryo if you candle a fertile egg on Day 4. If the embryo dies at this point, you may still see a faint network of blood vessels inside the egg's contents. An embryo dying at this point will show a large, black eye.
The fertilized egg (called an embryo) implants (attaches) into the wall of your uterus. This triggers the placenta to form. Your placenta begins producing and releasing human chorionic gonadotropin (hCG) into your blood and pee. HCG can be found in a person's blood around 11 days after conception.
Did you know you can determine if an egg is fertile or not by looking at the germ spot? The germ spot is the white spot on the yolk. The non-fertile germ spot contains only the female's cells and looks like a solid white spot. In a fertile egg the germ spot contains both the female and male cells.
Typically, you'll see a white circle within the yolk that looks like a bullseye (this is called the blastoderm). It's faded in color and not very large, but if you compare it to an unfertilized egg, you'll get the idea because it will be completely absent from the yolk.
Upon fertilization, calcium increases and zinc is rapidly released. When this happens, the zinc joins itself to small, light-emitting molecule probes. In other words, it creates a microscopic flash of light.
Put simply, yes. The egg float test works and is surprisingly accurate. People who do this test a lot can tell you with great accuracy how many days old an egg is.
You can eat eggs past their expiration date. Just be sure to keep your eggs egg-cellent by storing them correctly. If you don't know if an egg is good or not, you can try the float test or give it a whiff. If it doesn't pass the test, throw it away.
It's as simple as that! No artificial coloring is allowed in chicken feed, but some farmers will add marigold petals to give yolks an orangey color boost. Reddish yolks are made possible by adding capsicum (i.e. red bell peppers) to chicken feed, and throwing in a dash of paprika can have the same effect.
But again, the nutrition is the same no matter the color. Although egg yolk color does not mean it has higher or different nutrition, many people do think dark-colored yolks are more flavorful.
