You never know! They may have changed up the roosters and they are pure leghorn.
Do yours have spots or color on them?(the pullets not the eggs)
Of the six that hatched all were white no spots. Two were Roos and one hen escaped when she was very young. Never did catch her but I'm certain something did. Roos are gone.

I'll probably never find out who it is, but one of my 3 Andalusian pullets laid her first egg today!
e My first white egg from a breed that is supposed to lay white eggs.
I just placed her because I have so many that started laying. I miss those big white eggs every single day!
