In regards to dragons, however, there's one small point of which you should be aware: from everything we've seen of SR canon, including what comes from SR-canonical ED, dragons will do almost anything to a) get stolen eggs back and b) utterly destroy the individual(s) who stole them. According to dragon culture, it's the great dragons who ... hm. Call it 'provide a hatching ground' for dragon eggs; adults may mate and produce one or several eggs, but they will have already met with one of the Great Dragons and arranged for that GD to foster the egg.
What goes on while the dragonling is still in the egg seems to be a combination of childhood instruction and almost literal molding; the parents of an egg don't determine the hatchling's form, the hosting great dragon does, the hatchling emerging as the dracotype that the great dragon is. So a Western and an Eastern might mate and give the eggs to a Feathered Serpent - and the eggs will hatch into little feathered serpents. During the egg-time, though, the great dragon does 'speak' with the growing intelligences, teaching and molding them. I don't know if it goes so far as to teach them sorcery and spellcasting; you could say that it does. However, according to the ED information, at a certain point adolescent dragons go ... well, 'feral' is the best description. (And parallels to wyverns have been noticed.) They're very territorial, they kill each other, adventurers kill them, etc. etc. Eventually they cool down and enter into the Adult phase - but from the point where a hatchling is hatched to that adolescent stage is probably going to be quite a while, as in decades, and understand that in Shadowrun, the hatchling is not going to be MDC tough, as it were.
Great Dragons have been known to swipe eggs from each other (see Rhonabwy and the Sea Dragon for the best example - the eggs were turned over to Hestaby), but even that is a pretty major faux pas. Any company that got a hold of dragon eggs would be best off turning them over immediately to whatever Great Dragon they could contact, and apologizing profusely. If they didn't, well - neither the corporation nor its personnel would likely exist at the turn of the month.
