Kosher Eggs

Kosher Eggs


Only eggs from kosher fowl are kosher. These include chicken, Cornish hens, ducks, geese, and turkey.

The prohibition of eating blood applies even to the smallest drop of blood, and thus any blood spots found in an egg renders the egg non-kosher.

Each egg should be opened into a clear dish or glass and checked for blood spots before it is cooked or combined with other food. If a blood spot is found, the whole egg must be discarded, and the cup or dish should be immediately and thoroughly washed with cold water.

When boiling eggs, it is customary to boil at least three eggs at a time. Some people have a separate pot just for boiling eggs.

If a blood spot is found in a boiled egg, the whole egg must be discarded.

This is the reason why some have the custom to boil a minimum of 3 eggs at a time, so if one turns out to have had a blood spot, it will be considered "Batel B'Rov" - nullified by the majority of Kosher - and the rest of the eggs would be Kosher. In the hypothetical scenario you mentioned, since we don't actually find any blood spot, there is no reason for concern at all.

The egg is discarded because Jews cannot eat blood. If one has Non Jewish neighbors or friends, one can give the egg to them. Reply

Why is the egg discarded? Reply

Hypothetically, let's say there is at least 1/12 eggs has a blood spot and you were to boil the eggs, is that egg still kosher even though the blood spot does not appear after cooking? Reply

Although it is indeed problematic to drink milk that was actually milked on Shabbat, there is no problem drinking kosher milk on shabbat that was gotten at the local store. Reply

When you buy eggs in a grocery store, is a heksher required? I thought not, but then I saw one (I believe it was OU) on Eggland's Best eggs, and now I am confused. Reply

Now I was told, you can't drink milk on shabbos , as you do not know if the cow was milked on shabbos?
Oy. Reply

Oh goodness, there are so many wrong answers here. I am a chicken keeper for many years . I only keep hens,

Oh goodness, there are so many wrong answers here. I am a chicken keeper for many years . I only keep hens, no roosters. So there is never a chance I have a fertilized egg. Blood spots will vanish if the egg is old enough. It is a shame fresh eggs are turned away as they might have a spot. I often give eggs of all colors in my Shalos Manot baskets at Purim..but often wonder if they are just tossed out as my friends claim they will only buy store bought eggs ( which have not spots as they are old once they get to store!) My chickens are all free roam and fed non gmo organic, much better than store bought eggs! And the color of eggs has nothing to do with feathers! My black Aussie Australorp lays pink eggs! Reply

When it comes to blood spots, some people are saying it's a result of fertilization and other people say it is the result of a burst vessel during egg production in the hen. From what I understand, eggs bought in a store have never been fertilized.
The brown ones have more blood than the white ones, probably due to the difficulties of "candling" the darker eggs.
Where I live, "Free run" come in brown and white (boxes of 6), but "Organic" only seems to comes in brown. It is a shame that people think brown is healthier than white. Reply

The pigmentation of an egg is dependent upon genetics and the origination of the species, much like melatonin in humans. Blood spots are typically indicative of fertilization, which is usually arrested by removing them from the nest.The white eggs from commercial farms have been irradiated and are painted for uniformity. Brown egg layers are popular with organic and natural farmers because they tend to be from heritage breeds. Most farmers that use these methods also have strong feelings about preserving agricultural history. Like many modern foods livestock have been bred and even genetically modified for commercial purposes. Over the last century food has changed in its appearance. What is now an exotic fruit or vegetable used to be normal. Carrots are a good example, normal colors were red, white and even purple with orange being rare. The same with eggs, brown was the norm.

The color of a chicken's feathers is not related to egg color. The white earlobe of any chicken indicates white eggshells. Odd, eh? Red earlobes indicate eggs will have brown shells. There is no nutritional difference.
The one exception is Ameraucana hens who lay blue-green eggs.
Trust me. I have over 800 chickens of many breeds and learned this years ago. All our Ameraucanas have tufts of feathers sticking straight out of their ears and since they range in feather color, it's those ear tufts that tell me what breed they are and their eggs will be blue. Reply

My friend explained to me that the reason that brown eggs have more blood spots than white is that the process in egg farming of candling, or putting light behind eggs to look for blood spots, is more effective with white eggs than with brown.
Unfortunately, most organic eggs are brown, I believe for marketing purposes. The brown eggs are not more natural, but come from brown chickens, and the white ones are from white chickens. Reply

Other than blood spots, there really is not much other concern regarding fully-developed eggs from kosher fowl.

Some rare issues to be aware of:

Some partially developed eggs that are found inside of a slaughtered bird are considered to be "meat" and may not be eat with dairy.

An egg--even if is fully developed--that was found inside of bird that was not slaughtered according to Torah law is problematic.

About what goes into ensuring that the actual chicken is kosher, I suggest that you have a look at this article Reply

Just a quick observation. I am struggling here with this one, especially as one who has raised livestock and eggs for food. I can understand kosher eggs from clean chickens or from chickens that are thought to qualify as Kosher, but there are other issues in slaughter and meat handling that might disqualify any clean chicken as non-kosher. .... or have I missed the section on kosher live animals? Please point me in the right direction. Thanks. Reply

Great questions. To understand more about blood spots in eggs, I recommend this article (from the Orthodox Union): Reply

If a boiled egg with a bloodspot is not kosher and needs to be discarded. What requirements are placed on a kosher restaurant when offering boiled eggs as an option on its menu? if it serves a non kosher boiled egg would it lose its licence? at what stage is the non kosher egg actually deemed to be not kosher?
