No, but most of them are. It depends on the personality of your individual rooster, but being loud it pretty much in their nature. It is not something that can be trained out of them.
They are called roosters.
I'm pretty sure all male chickens (AKA Roosters or cockerels) have tail feathers. Actually, roosters are the pretty chickens with really really long tail feathers. If a male chicken is lacking tail feathers, they were probably pulled out by an outside source.
The females from all breeds of chickens lay eggs. Some hens stop laying when they are old, but there are no breeds or varieties of chickens in which the females do not lay eggs. Roosters, as the male of the species, never lay eggs.
All chickens roost.
They are both! Most of the chickens in the super markets are raised especially for meat use and grow so fast (heavy) that they are useless for breeding or pets. They are generally crosses between cornish and rock breeds. The roosters may reach market weight a few weeks sooner then the hens but they will soon follow.
Yes. As cockerels (As Male Chickens Younger than a year are referred to) grow into Roosters they begin to become sexually mature. Roosters, if not seperated when they are fully grown will begin to fight. The reason the Roosters fight is because they want to become top of the pecking order (you can research this more if you wish) but mainly want to become the leader of the flock so they have all rights to the hens. Any other Male is considered an 'intruder' wanting to battle over the rights of owning the flock. If two Roosters are placed together they will fight and often to the death. This is why you must separate Male Chickens to ensure they don't fight and become aggressive.
No. There are some breeds of roosters who do not.
A hen is an adult female chicken.The set of all hens is a subset of the set of all chickens.
Chicken's have no actual genitals. All birds have a system called the cloaca, which is an opening that allows everything to go though. Male's do not have the *ahem* usual bits but instead have a small sperm glob that produces on cue.
There are many, many breeds of chickens, and there are roosters of all breeds. So that is a very open question. Roosters can be any breed of chicken.
Chickens have features such as a beak, comb, wattles, claws, and feathers. They also have a small body with two wings and two legs, and their feet have four toes. Chickens come in various colors and patterns depending on the breed.
My chickens and roosters and my two cats all get along really well together. If the chickens don't want the cats around they chase them out of the pen, other than that they they all get around together.
