not sure about all hens but my hen bonnie will sit even if bert the rooster is around she does not seem to mind
No. The rooster has relations with the hen and she lays fertilized eggs
They sit on them as soon as the egg is laid. They will continue sitting on the eggs until they hatch. This keeps the eggs warm. If you gather the eggs every day, the hens are less apt to sit on them. Sometimes their maternal instincts kick in and they will sit on the eggs. When that happens you can just reach underneath and pull the eggs out. They may peck at your hand, but it doesn't hurt.
A broody chicken is when a hen decides to sit on her eggs... even if there is no rooster around, and even if the eggs belong to a bunch of random chickens on the flock... they will just sit on the eggs hoping to hatch them out, i guess.
No, absolutely not. Hens sit on their eggs until they hatch. They actually nestle their feathers above and around the eggs and keep them warm, but people say they are sitting or setting on their eggs.
sit on the eggs
No. A broody hen is a broody hen and will sit on golf balls once the urge to nest takes her. Hens do not instinctively know if the eggs they are brooding are fertile or not. Hens in a chicken coop without a rooster among the flock will still go broody.
A hen goes broody, which means she wants babies and will collect / sit on eggs. The eggs MUST be fertilized by the rooster to have baby chickens. The hen will sit on the eggs for average 21 days. During those days, the heat of her body heats the eggs, allowing the embryo to form. Right before hatching, the embryo will suck the yolk into it's belly, so that when it is born it doesn't have to eat for up to 2 days. The chick hatches, and the mother hen takes care of it.
They sit in the hen house on eggs, on the roost or in a nest.

A Hen needs to be mated before sitting on a clutch of eggs..
No. Only hens lay eggs but hen hatched eggs are only found on small farms. Most fertilized eggs are artificially incubated and the chicks never see the hen who laid them. Chicken do not really benefit from the mother hen all that much anyway. Chicks are born able to feed themselves and instinctively know how to be a chicken. If you are asking if the rooster helps the hen incubate the clutch of eggs, then no, once the rooster has mated with the hen he is not involved.
