Although they each have their own separate rules, fish and eggs are both classified as pareve, or neutral, which means that they do not contain milk or meat. Eggs that come from kosher fowl or fish are permitted as long as they don't have any traces of blood in them.
» The word kosher, literally meaning “clean” or “pure,” refers to food that has been prepared in accordance with Jewish rules and rituals so it can be eaten by religious Jews. So are shellfish, lobsters, oysters, shrimp and clams, because the Old Testament says to eat only fish with fins and scales.
Only the eggs of kosher species of birds are considered kosher. Also, they must not have been laid by a bird that was a Treifa, defective, or removed from a Nevaila, the carcass of a dead chicken. The Talmud discusses the means by which one can verify the kosher origin of an egg.
All frozen vegetables are acceptable, with the following exceptions that would require a reliable hashgacha: Broccoli, Brussel Sprouts, Asparagus, Cut Onions, Spinach, Potatoes, Artichoke Hearts.
Kosher meat must come from an animal that chews its cud and has split hooves. (Cows, sheep and goats are kosher; rabbits, kangaroos and fox are not). Kosher fowl are identified by a universally accepted tradition and include the domesticated species of chickens, Cornish hens, ducks, geese and turkeys.
[Meat spots or blood spots] are caused by the rupture of a blood vessel on the yolk surface when it's being formed or by a similar accident in the wall of the oviduct… As an egg ages, the yolk takes up water from the albumen to dilute the blood spot so, in actuality, a blood spot indicates that the egg is fresh.
Isolate the recovering hen from the rest of the flock (which might be tempted toward cannibalism). Feed her drastically reduced rations for a week to slow up the egg laying. But supply plenty of fresh greens and water. Clean her vent area each day and apply ointment.
Chickens stop laying eggs for a variety of reasons. Hens may lay fewer eggs due to light, stress, poor nutrition, molt or age. Collect farm fresh eggs from your backyard flock. As the days become shorter and temperatures drop, you may notice fewer eggs when you go out to the chicken coop.
A: When a hen has just begin laying, there can occasionally be a little blood on the egg shell, but it is usually no cause for concern. Eventually her vent gets used to stretching when she lays, and becomes very elastic. However, at first it does occasionally happen that with a large egg she might bleed just a little.
Prolapse vent in chickens is an avian anomaly wherein a hen's vent or cloaca is inverted and pushed to the outside of the body.
Chickens and menstruationFemale chickens have a menstrual cycle, during which a hen's ovary sends a yolk on its path. As it moves though the reproductive tract and into the shell gland, then yolk then forms into an 'egg white'. The shell takes about 20 hours to form.
Egg binding, or having a retained egg, describes a situation where an egg is physically stuck inside the hen. When hens are “in lay” they should lay an egg approximately every 25 hours. While egg binding is rare, it should be treated as an emergency since the inability to resolve the problem can result in death.
The colour of the lobe varies with the breed of the chicken, ranging from white to almost black. Chickens with white earlobes lay white eggs exclusively while birds with dark lobes lay brown eggs.
The follicle is a fluid-filled sac that contains several blood vessels. It may burst during the egg-laying process, and if any blood vessels rupture, blood can deposit on the egg yolk. Blood spots can also occur in the egg white, which means that the bleeding occurred after the egg was released into the oviduct.
Black or green spots inside the egg may be the result of bacterial or fungal contamination of the egg. If you come across an egg with black or green spots inside the egg, DO NOT EAT. Off color egg whites, such as pink, green or iridescent colors may be from spoilage due to bacteria.
Look for any pink, blue, green or black discoloration in the yolk or whites, as this may indicate bacterial growth (3, 4). If you notice any signs of discoloration, throw the egg out and wash the bowl with hot, soapy water before testing a new egg. You can also check to see if the whites or yolk of the egg are runny.
With proper storage, eggs can last for at least 3–5 weeks in the fridge and about a year in the freezer. The longer an egg is stored, the more its quality declines, making it less springy and more runny. However, older eggs are still good for several uses.
Sometimes, a bright red spot, called a subconjunctival hemorrhage, will appear on the white of the eye. This often happens after straining or coughing, which causes a broken blood vessel on the surface of the eye. Most often, there is no pain and your vision is normal. It is almost never a serious problem.
Summary. When eggs spoil, they begin to smell bad, and the yolk and egg white may become discolored. The main risk of eating bad eggs is Salmonella infection, which can cause diarrhea, vomiting, and fever.
The color of an egg is not an indicator of quality. When it comes to taste and nutrition, there is no difference between white and brown eggs. Despite the fact that they're often more expensive, brown eggs aren't any better for you than white eggs, and vice versa.
The white spot attached to the yolk is called the “chalazae”, which serves to hold the yolk in the center of the egg. The chalazae are often not noticeable in store bought eggs because it is absorbed by the white as the egg ages. The chalazae is a sign of freshness and not harmful or bad.
