No. Hens will lay more when there is less stress put on them, and having roosters - especially too many per hen, too large of a rooster, aggressive roosters, etc - will cause the hens a lot of stress.
4 hens per rooster is a better ratio. Roosters often "rough up" the hens when they breed, so having more hens will prevent any one hen from being picked on too much. I know lots of people who feel like 8 hens per rooster is about the maximum the average rooster can handle.
If you have more than one rooster in a flock of hens, you will have cockfights. Sometimes, they will fight until one or both of them die. You only need one rooster to fertilize all the eggs anyway. Most people have the extra roosters for Sunday dinner - and not as a guest, if you understand.
All roosters crow. There is no breed I am aware of that makes no noise. Crowing is a big part of the roosters job, he is the guardian of the flock and must keep the flock alert and danger away. This is done partly by crowing.
Only two that I can think of. Adam and Eve. Any animal that could be useful to the members of that community. Chickens for eggs and meat and roosters for continued renewal of the flock.
There is no egg. (Roosters do not lay eggs).
No. A rooster can stay with the hen and her young at all times. It is best not to introduce a new hen with young to your flock.
They eggs are the same size as if there is no rooster in the flock.
There is no reason why you should unless the rooster is overly aggressive toward the hens. Roosters protect the flock and of course mate with the hens so unless you have an objection to fertilized eggs, then allow the rooster to be with his flock. Roosters are sociable creatures and should be allowed to mingle with the other birds.
Actually, roosters are usually the only kind of chicken eaten. Hens are kept for egg laying and a few roosters stay on a farm to fertilize the many females. Since few are needed to keep the flock fertile, the roosters not eaten (There are a large excess of them after the eggs hatch) are sold to food processing plants. I hope I have answered your question.
roosters fertilize the eggs but they dont raise the chick

our roosters don't fertilize our eggs it would be good if they did
