Question on packing peanuts

[chickie fam]

I have an order in with MPC for 10 Delaware pullets and I was wondering, what the chances are for getting packing peanuts? If I do get packing peanuts are they cockerels or pullets? And are they usually of the same breed or just whatever else they had around of the time of shipment?

Cockerels and whatever they have lying around (packing peanuts are usually the same breed as each other).
