The answer to this generalized question could very well form a thesis for a university graduate.
I will provide you with a good link for you to do your own research into this massive subject.

Chickens are very vulnerable to parasitic infestations, such as scaly leg mite, wich is caused when the mite burrows under the scales on their legs, and push up the scales with their droppings! I find that chickens with feathery legs are very prone to this. Chickens also suffer from lice, and worms. Their crops and gizzards can become impacted with food. Chicks can suffer from potentially fatal coccidosis, where they get depressed, huddle in a corner, fluff up their feathers, turn pale and suffer from diarrhoea. One of the most common diseases of poultry is mareks disease, which causes tumors in the nervous system with varying degrees of paralysis. There is an expensive vaccine for day old chicks that is used commercially, but it is not cost effective for back garden birds.
Lack of vitamins in feed can cause feather loss but usually novice farmers mistake a normal molting period for some kind of disease. All chickens have at least one molt per year which will last as long as six weeks. At this time egg production drops and chickens will lose feathers. New feathers will re-grow.
Yes, it's just like passing AIDS from mother to daughter during pregnancy.
Mareks, Typhus, Coccidious, Pullorium. Those are the most prevalant.
They get a lot of different diseases.
The one that is usually most relevant to people is salmonella.
My uncle had them and when that happened it was because of lice.

No, but chickens have their own raft of diseases.
Yes, turkeys can and will often catch diseases from chickens. This is why it is advised to keep turkeys and chickens separate, this way the turkeys cannot catch the disease from the chickens.
yes
The disceses are from humans having sex with them
Two common gastrointestinal diseases are endemic Newcastle's Disease and low-path avian influenza; both of these diseases circulate in the wild bird population, so any chickens exposed to wild birds are susceptible. There are other diseases, but the frequency of them varies depending upon where you are located and how much exposure your chickens have to the outdoors. Common parasites include mites, ticks and fleas; most chickens control these through dust baths and frequent grooming of their feathers, so unless it gets severe you don't need to worry about treating the chickens for these.
It depends on what your definition of "better" is. Chickens are a food source. They provide meat and eggs. Squirrels are not a sustainable food source. Chickens carry diseases such as aviation flu. Squirrels carry diseases such as hemorrhagic fever. Chickens are not cute (to most). Squirrels are cute (to many). Chickens can be domesticated and farmed. Squirrels cannot be domesticated because they are classed as a pest.
Fayoumi. They can fight off any bacterial infection.Count Olaf
it can transfer diseases to human like bird flue ... !

No, we don't know if the raccoons were sick or had any diseases that can be hazardous. The chickens will not be safe around kids. They simply could transfer germs or bacteria from the raccoons to the kids.
Chickens can die from many diseases, but most tend to leave to 10 years if allowed. Most chickens are killed at 2 years old, while they are still very young.
Precautions to take to prevent disease among chicks and the poultry are to keep a clean coop, remove any diseased chickens from the rest of the chickens, provide immediate medical attention to wounded or sick chickens, and provide a healthy wholesome diet.
