Factory farming is nothing if not efficient animal husbandry at a massive scale, and that's just what these hens do. If you're wondering where the brown eggs come from, they're typically laid by larger, heavier breeds like Rhode Island reds or Plymouth Rocks, which eat more and produce fewer eggs than leghorns.
The brown colour on so-called brown eggs comes from a pigment that is put onto the outside of the shell very late in the laying process, and if you get the egg immediately after it has been laid, you can actually clean the brown pigment off because it hasn't yet had the time to set.
Indeed, brown eggs are very common in Australia amongst commercial producers and even pastured egg producers because they typically raise hens that lay brown eggs (ISA Browns or Hyline Browns). These breeds of hen lay pretty much every day, and so this makes these hens very 'productive'.
However, during the late 1970s the number of white eggs began to diminish as consumers expressed a preference for brown eggs.
There are other reasons white eggs are preferred compared with brown. The white shell is thinner and easier to crack without breaking the yolk for instance. Some people prefer brown now because it's seen as more ``natural'' though the brown eggs go through the same production process, but come from a different breed.
The main reason blue eggs might cost you a few more bucks is simply scale. “It's more expensive to produce a blue egg than a white egg, specifically, but even a brown egg,” Steele said. “The breeds that lay white eggs are generally the smaller breeds of birds so they eat less and are cheaper to raise.
The main egg colour available in Australia is brown, although a small number of farms also sell white eggs. While many people assume brown eggs are more natural and therefore healthier, that's not the case. Brown hens lay brown eggs, white hens lay white eggs, and they both have the same nutritional profile.
There is no nutritional difference in the two colors of eggs. Both are good for you and part of a balanced diet.
According to USDA, eggs are not a genetically modified (GM), or bioengineered food. This includes shell eggs and eggs used for processed egg products.
This partial protection allows Australian eggs to be safely kept on supermarket shelves at room temperature in Australia, whereas the American system removes this protective coating and therefore requires eggs to be fridged.
In the end, the rarest color of chicken egg, blue-green, adds a delightful dimension to your backyard flock. As backyard chicken keeping continues to grow in popularity, so does the desire to collect a more colorful basket.
There is no benefit in eating fertilized eggs. There is no nutritional difference in fertilized eggs and infertile eggs. Most eggs sold today are infertile; roosters are not housed with the laying hens. Fertile eggs with cell development, which is detected during the candling process, are removed from commerce.
How they are made The fake egg white is made by mixing sodium alginate to warm water, and then adding gelatin, alum and benzoic acid to the mixture. The same mixture is used to make both the yolk, by adding a yellow colouring agent, and to make the fake egg membrane, by adding calcium chloride to it.
The eggshell colour depends on the breed of the hen. Generally speaking, white shell eggs come from hens with white feathers, while brown shell eggs are produced by hens with brown feathers. Nutritionally, both brown and white eggs are identical unless the feed has been enhanced for speciality eggs such as Omega-3.
But the reality is that eating the whole egg provides a lot more nutritional value. "Egg whites contain a small amount of B vitamins but, for the most part, all of the other vitamins, minerals and antioxidants found in a whole egg are lost if we're just eating the whites," explains Arrindell.
Excessive cooking at high heats can deplete eggs of their antioxidants. Antioxidants are healthy nutrients that protect your body from those harmful free radicals. One study found that boiling, frying, or microwaving can reduce the antioxidant content in eggs.
Regardless of their shell color or farming method, all eggs contain the same vital nutrients unless they have been fortified. If eggs are noted as nutritionally enhanced, their labeling will specify which nutrient content has been altered.
In fact, the American Heart Association considers eating one full egg or two egg whites daily, as part of a healthy, balanced diet. “This suggests moderate egg consumption for the average, healthy person doesn't necessarily risk our heart health,” adds Dr. Sampino.
100% of the fresh poultry and eggs used in our Australian products are produced from farms regionally across Australia. Our suppliers are all trained in relevant sector-specific requirements e.g., RSPCA Approved or FREPA as well as meeting Woolworths' Supplier Excellence Programme standards.
It's no secret, that eggs are in short supply. Unfortunately for consumers, when demand exceeds supply, prices also go up. The outbreak of avian influenza (bird flu) in 2024 led to the culling of nearly 1.8 million birds to prevent the spread of the disease.
Key Facts Endemic to Australia: The Black Swan (Cygnus atratus) is native to Australia and is the only naturally occurring black swan species in the world.
There's a difference between farm fresh eggs and store bought eggs, and that is the membrane. The membrane will cling on to the shell of the egg, being more tightly bound the younger it is. When doing hard boiled eggs with farm fresh ingredients, you want to make sure they're aged at least 3-4 days old.
An undercover video shot at one of the egg producer's facilities showed rough treatment of hens and poor living conditions that prompted an investigation from United Egg Producers (UEP), an animal welfare organization that certifies healthy living conditions.
That's when they are telling you that their start up cost to build the Coop and all items associated are $3,000 and it gets put to the first egg.
