She should be ok. If not don't isolate her. Isolate him dor a few days.
There has to be a rooster around to get any chicks out of the eggs.
rooster and chicks it depends on how big the egg
No, he will not hurt his chicks in any way and will defend them like my rooster does.
Usually the rooster will ignore the chicks unless he is a particularly aggressive male. The mother hen will guard the chicks but cannot keep them safe all the time. If you have space to separate them do so. If the birds are free range then you will have more problems from aggressive hens than from the rooster.
A rooster will never brood the eggs, but he will defend his chicks. Although my rooster one time did brood when we first got him he stopped the next day, he only did it because the hen was already sitting on the eggs.
Only if you want to hatch chicks. Then, no you don't have to.
they are called pullets and rooster chicks are called cockerels

If you don't care if they are purebred you can get any breed of rooster. ..prinsesrau answer.... hens can have part rir chicks if there rir or if the rooster is. yes it depends if u weant pure rir if that is the case hen and rooster need to be rir
basically you have a fifty fifty chance of getting a black chick or a grey chick although I find my chicks tend to take after their mothers
A group of chicks are called clutch or chattering.
yellow
If you mean , should a rooster be allowed to be in same quarters as chicks, absolutely not. They will peck at chicks and not allow them to eat. The same goes for any hen that is not their mom. They are very mean to all younger birds.
