How long do I need a hen and rooster alone to ensure purebred eggs

[pnp4kidz]

I have three roos, in with my three maran hens, and one mutt hen. How long do I need the other two roos out of there before I say the eggs are pure?
at that point I also need to check fertility...

how long is a roo fertile? he is probably 3 years or 4 years old, is he too old?

same with hens... how old is too old? they still lay, just not daily anymore... they are three I think... will they still lay 'good' eggs?

I never EVER see them mating... are they shy?

Thanks, from a newbie...

Most people say 30 days separation from the previous roos.

After that you should check the eggs for fertility to see if the remaining older roo is doing his job.
