Make a zeppelin and build a box on top of it. Next get a oviraptor on follow just behind you inside said box. Fly over to a nest and land on the nest and stop driving the zeppelin. Turn around and take egg from oviraptor without aggroing wyverns then fly and repeat.

Wyverns may occasionally still aggro but they don't stop after awhile your zeppelin can take the hits and hopefully get close to wild dinos to get wyvern to aggro on them.

Aside from that only risk is if oviraptor clips through zeppelin if not careful.
