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.
A group of roosters is called a "flock" or a "crowd."
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.
Roosters crow in the morning and throughout the day as a way to establish their territory, communicate with other roosters, and alert the flock of potential dangers.
Yes, they will fight for possession and control of a flock.
Roosters crow all day to establish their territory, communicate with other roosters, and alert the flock of potential dangers.
Yes, they do. Roosters will attack other roosters, people, hens, and even their own baby chicks.
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.
Better to say 4 roosters is too many for 4 roosters. The 6 hens can wait a bit and soon there will be one rooster a-go-go, one in the hereafter, one running away, and one squating on the ground. The hens could deal with 6 roosters, but the big boy a go-go won't stand for more than him with his flock. actually 1 rooster needs 5 hens to be satisfied other wise roosters will fight One rooster will service (fertilize the eggs of) up to 6 hens. If you have more than 6 hens, you will need another rooster. 4 roosters on 6 hens is not good. The roosters will fight and the hens will be exhausted running from all the roosters.
Young roosters don't really need to be separated from the flock, unless they are fighting & causing damage to each other (which they can & will do).
Roosters are fairly dumb and would not remember that event after a short time. A group of hens is called a brood and not a flock. Roosters don't really care about sheep so I was assuming you were talking about a fox catching a hen or two. He should have forgotten that the next afternoon.
Roosters make this noise to calm and reassure the hen all is right with the flock. Roosters have many ways to communicate with the hens such as crowing, which is a call to other roosters to let them know he is guarding the flock or to let the hens who have wandered away from the flock to come back.
Everything. They interact with their flock, both with hens and other rooster, the farmers who take care of them, the predators who bother the flock and the insects and rodents that inhabit the areas they share.
