Gift Egg PIDs (Riley Riolu, ect)

[Soladept]

While examining my pokemon in my Plat/Diamond saves, While going through hatched gift pokes like the Riley Riolu and Cynthia Togepi, the PIDS are all type 1s, as in, they are generated like standard gifted pokemon, ect, instead of the usual rules when it comes to eggs.

I am mostly bringing this up so folks that edit/create these pokemon have some knowledge about how the Legit PIDS work, if this hasnt been brought up before.
