There is more information on that strain of Delawares at this BYC thread- most are on Facebook also.

Good luck on your search .
Chris - I don't think white has a bearing on Hawk kills in Dels . They are fairly good size and here most Hawk prey is dark [Turkey polts etc]. All my Hawk loses have been black broilers. I have lost two Dels to I presume Owls because it was night and the chickens were not supposed to be out...
Bobby - its not a problem its just learning - If you just want eggs and chicken friends hatchery will fit the bill - if you want a homestead bird with a little less egg production but meat potential find a quality breeder. Good luck - Either way its a great breed.
Odds are higher they are pullets but all lines are different . Depends on the strain. Had one last year at 16 weeks tail said Cockerel and comb said pullet - finally determined pullet at about 20 weeks
