The only time a chicken will lay an egg with a chick inside is when there is a rooster around, which he would fertilize the eggs. If there' s not a rooster around to fertilize the eggs there won't be any chicks and each egg would only have the egg white and yolk. It can vary on how often they lay eggs, depends on the weather the amount of daylight and so on.
