Eggs, the side or main component of your breastfast... Most people don't really consider what an egg really is. A chicken has a menstruation just like us females, we both release the egg  from our body at this time so essentially an egg is a chickens period. Chickens however lay their eggs and excrete their waste from the same spot called the Cloaca which means eggs come in contact with feces and urine.

An eggs is normally not fertilized meaning there is no fetus inside but some cultures do eat eggs with such. But rest assured the ones you may have been buying from the store are unfertilized (unless by chance a rooster was present like at many family run farms).
So if there is no baby inside why do vegans care? Well focusing on the ethical side of things and not the health of environment. The female chicken bred to make the eggs probably had all her brothers ground alive, suffocated or gased. In the egg industry when they bred more egg laying hens the only problem is they can't control the gender. Males are useless to the egg industry so less then 72hrs after hatching the males are ground alive in a macerator, suffocated in a bag or gassed.

Aside from the males being killed the females are debeaked by using a hot blade. The beak is filled with nerves like any part of an animal farmers cut off, this can lead to chronic pain. This is done to prevent birds from pecking at others but this wouldn't happen in the first place if there were not in such stressful situations. 95% of egg laying hens spend their lives in battery cages because of this the end up with severe feather loss, disease and sores. Like I had stated before, chickens today have been genetically modified to produce more then 300 eggs a year.

Force molting a nice way of saying starving the birds for 2 weeks. This is done when egg production declines in order for the bird to lay more eggs. Hens should be able to live 5-8 years but egg industry hens live 1-2 years and are sent to slaughter when spent. Chickens and turkeys are exempt from the Humane Slaughter Act so they are fully aware when their throats are slit. But it's common from large amounts of hens to be gassed to death and as undercover investigators have found many are still alive after.

Environmentally 477 gallons of water are required to produce 1lb. of eggs. 5% of water consumed in the US is by private homes. 55% of water consumed in the US is for animal agriculture. Taking a shorter shower will not save water on the grand scale that cutting animal products out of your diet would.

Health wise eggs are your worst enemy. The egg industry it's self is not allowed to say eggs are healthy, nutritious or safe because this is false and misleading advertising. It's against the law, look into it. People not getting paid by the egg industry such as some you tubers or bloggers are allowed to say these kinds of things, but go watch some egg commercials you won't hear those 3 words. You might hear nutritionally dense, full of protein or the perfect start to any morning but thank goodness it's illegal for them to spread anymore lies. Eggs are very high in cholesterol which causes plaque build up on the walls of arteries increasing blood pressure until BOOM there's a heart attack or stroke. The first sign in males of heart problems is actually Erectile Disfunction because the smallest arteries are in the penis they are about half the size of the hearts Arteries therefore tend to get clogged first. (Females can also get ED) If you get treatment for ED you are 2x as likely to get treated for heart problems later+ if you are over 50 you are 50x as likely to die of a heart attack.

Blood cholesterol (serum cholesterol) increases when dietary cholesterol is added (only animal products contain dietary cholesterol). Some people argue this with studies... That just so happen to be funded by the egg industry. So how is this possible? The egg industry knows how to trick you. If you didn't know already serum cholesterol can only go so high, our body can only have so much. So knowing this the egg industry designs studies using people who already have high serum cholesterol levels. When fed diets high in cholesterol their serum cholesterol cannot go any higher therefore they conclude dietary cholesterol does not increase serum cholesterol. Studies can also be manipulated by calculating serum cholesterol hours after eating "fasting cholesterol" when the dietary cholesterol has lowered, this is also when heart attacks are least likely to happen.
