Fertile egg production

[SA gardener]

Suppose I was to buy a rooster and keep my hens purely for breeding, could they produce the same amount of eggs that the particular breed (Australorp) I am using normally lays in infertile eggs per year - 300 eggs (no rooster).
Considering I remove the eggs after they are layed and put them in an incubator followed by hand rearing .

I know that if I was to start a business, it would be best to buy books and consult experts but I'm just asking out of curiosity (the lockdown boredom is stirring up ideas)

Egg production would remain the same. You'd just have another mouth/s to feed. Having a rooster/s and fertility of eggs should not effect quantity of eggs being laid. Keep in mind-hens that lay 300+ eggs a year go down in production quickly with each year of age.
