the chicks will be many
as many as 18 eggs at a time. It takes about a month for the chicks to hatch.
a number of young hatched at one time, a family of young, is known as a Brood
In one season there could be anywhere from 60 chicks to 110 chicks in one breeding season
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.
Just let her be. The newly hatched chicks will take up some of momma's time and the room under her but the mother hen will adjust things by herself. Trying to do this for her will just stress her out and may cause her to leave the nest. The new chicks will find room under her wings eventually and mother hen will roll the unhatched eggs closer together.
The mother is most likely just protecting her chicks. Mother hens are often very protective of their young, especially newborns. This is not an uncommon thing. Try showing the hen that you won't hurt her chicks. I can't give you a lot of helpful advice on how to do this, but I am sure the Internet will help. Good luck! =)
Anything they feel like at the time.
It depends on the species of bird. In many species, the male does not help rear the chicks. In some species, such as the ostrich, the male spends a good deal of time taking care of the chicks.
