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.

It's my understanding that brown eggs are more likely to have blood spots because during inspection, when a bright light is shined through the eggs (candling), any blood spots would be more visible in a white egg and those are discarded before they reach the grocery store.
Happy to see some of the breakfast restaurants are now advertising their use of only "free-run" eggs Reply

I take out spots from free range eggs and remove the stringy tissue. It may not be kosher but it is not a total waste of food. Reply

White, Cage-Free is the Answer But mine has to be Kosher. They are more expensive but I wanted to do the compassionate thing. I got white, cage free last time-no blood spots. The spots don’t mean they are fertilized. The spots come from the fertilization process, but they aren’t necessarily fertilized. There is a process farmers use to spot these anomalies, and they are checked by humans also. The answer to my issue is to buy white, cage free. Reply

I noticed brown, free range eggs have blood spots on them. Is there a reason for this? I’ve had to throw out a lot of those types of eggs. Reply

Duck eggs Which duck breeds are considered kosher by Chabad standards? If one wants to buy duck eggs, is hashgacha necessary to ensure that that the eggs came from a kosher duck? Reply

In order for birds to be kosher, most authorities require a tradition about the bird. If they ate it in previous generations, then it may be eaten today. If we don't know, then we don't eat it.

This applies even to different breeds of fowl. Muscovy duck has been a long source of debate, along with mallard ducks with black beaks.

Therefore, a hashgacha is needed for duck and duck eggs.

However, once the breed has been established as a kosher one, then the eggs do not need hashgacha. So, if you know a farmer who has only kosher ducks, you can eat the eggs without a specific hashgacha. Reply

Duck eggs Thank you. Please answer my first question: Which breeds of duck have been determined to be kosher by Chabad rabbonim? Reply

Re: Kosher or Not 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.

To Becky 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

Kosher Or Not? 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

Re: Milk on Shabbat 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

Hekshered Eggs 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

kosher breed hen Oh goodness, there are so many wrong answers here. I am a chicken keeper for many years . I only keep hens,
which breed leghorn ?not all breeds are close enough to be considered that they are with the mesorash kosher as remu wants Reply

wrong answers! 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

Each hen should have her own condo and HD tv in order to be deemed kosher a remote control that can be beak operated is optional Reply

Conflicting information 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

Brown and white eggs 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.

brown/white eggs 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

Brown eggs and white eggs 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
