What Age dose a BSL and a White Stars lay?

[BlackRock13]

I recently found out that my *white leghorn* was a White star. Since I could not find an answer on the internet I was hoping to find out here.Also, I was hoping to find out about my BSL point of lay. I did read they lay at 18 weeks or more but is it correct?

Btw- These chickens are 15 weeks so that why I wanted to know and could someone also send a picture of a White Star at 16/17 weeks.

A lot to ask but thanks for reading!

white leghorns and white stars are the same thing. they should start at the age of about 5 months.
