We should mention there are two kinds of baby mags on Ultima: the normal mag your new characters always start with, and a special quest reward mag from the quest Power Plant Plight. The normal mag you receive is lv 5 when you receive it, the special quest mag, on the other hand, is level 0, giving it 0 DEF making these feed plans possible. A lv.0 baby "ppp mag" is worth about 5 pd or so.
