When will my pekin hen start laying

[bird lover 34]

I have a Pekin hen about 5 months old. When will she start laying? I also have a young drake, about 4 months old. When do I have to worry about fertilized eggs?

'Worry' about fertilized eggs?
They should lay around 17 weeks, but Pekins are meat breeds, not layers so it'll be later
