They live together 24/7
Not typically. Any breed of hen can make a crowing sound but it is often done by hens in a flock that has no rooster. The alpha hen in a flock of chickens without a rooster will often take over the "guard" duties of a rooster.
rooster
This is mating submission behavior. The see you as "the rooster". Most often this happens to the person who feeds and takes care of the hens, especially when no rooster is present within the flock.
no. they will lay without a rooster
A good ratio is 1 rooster for every 15 hens. Many farms keep more hens than that and only one rooster, but that keeps him very busy.
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.
Yes, a rooster will be happier with hens around.
Yes, a rooster is a male chicken. Hens are female.
usually the ratio of hens to rooster is about 15 hens for every rooster. If you keep them separated an extra rooster is not a problem but in a flock of 24 hens,you will have some squabbling between the dominant rooster and the #2 .
One rooster for every 10 to 15 breeding hens. This is for medium to heavy egg layers. Fighting is possible even when the ratio is much higher split flocks may be required or more docile rooster added to the flock if it becomes a problem.
Nope.
No. Chickens will lay perfectly good eggs without a rooster. In fact, many people prefer not to keep a rooster, because they don't want to find a fertilized egg that was a little too far along.
