how to make a Crele Orp ??

I am seeing these eggs on E-Bay and was wondering how
one can make the Crele Orpington at home ......
I know that years can go into getting a nice bird like this with
dedicated commitment to achieve a certain strain or look.
but for the BackYard Enthusiast, how can one get close to this look ?
All the egg sellers say it is VERY VERY RARE !!
But, then they go on to say the hen lays 250 eggs per year.
Seems to me, that after a couple of years, you would be overrun
with them..... then, they would not be so rare ??

 

couldn't get the pic to post . . . .
