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).
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.
The items should be separated by commas.
It is preferred to have one rooster for every 5 to 6 hens
Hens "talk" a lot more than roosters, but are not particularly loud. The rooster "crows" once in a while and can be quite loud.
No The laying mash or pellets are fine for the rooster. There really is no way to stop the rooster from eating the same things you feed the hens other than keeping them separated. My hens are fed laying crumble all year long and the roosters thrive on it.
Not without starting a fight.
It may as hens generally are larger and have more meat to them than roosters and the size of the bird determines how long it needs to cook.
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.
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.
If you are legally separated on the last day of the year, you should file either as single or as Head of Household (if you have children that live with you for more than 50% of the year).
Fragments are separated by size with smaller fragments migrating more quickly than larger ones.
I don't really know, but i think he likes chicken fat better than rooster fat but he is a chicken/rooster.
