Answer
It is the roosters job to protect the flock. They are the first line of defense when a potential predator comes along and YOU are a potential predator. He will do his best to scare you off or at least give you a "victim" to eat while the hens run and hide.
Roosters can not crow if they can't fully extend their necks.
roosters crow to reestablish their territory
The real question is: Who trains roosters to crow at sunrise?
We have the same problem. We have tw roosters and 28 hens. They are the White Leghorns. Generally the roosters take turns crowing. Lately the flock has been molting...it looks like snow in our coop. The roosters are not crowing. I have looked for an answer as you have. Interesting we both have the same problem. It looks like molting may have something to do with them not crowing.
The Roosters
Yes they will.
No, they have no teeth only a beak, so they "peck" not "bite"
I'm not certain that either of those words accurately describe what roosters do. They can peck with their beaks, or slash with their spurs.
Probably not and if it was it would not be fair for the chicken who would prefer to peck around ouside.
No, roosters tend to not like having other roosters around
Its not usually the rooster you need to worry about. Most roosters just ignore the chicks. It's the other hens in the flock who will peck at the young ones. One misplaced peck will wound or stun a chick and unless the mother hen protects the little one the other hens will come in for the kill. Often the mother hen is guarding the other chicks when one gets into trouble. Whenever possible, it is best to keep the brood hen and chicks away from the other members of the flock until they are old enough to escape unwanted attention.
Roosters are birds.
roosters do not have babies
No, roosters are boy chickens
Peck is bigger
Usually, it's just because he is mating with the hen. The rooster will mate by standing on the hen's back and holding on to her neck feathers with his beak. Roosters usually don't actually attack hens.
Yes, roosters have a spine. They are vertebrates.
