Why is the spawn rate in juvenile wyvern so poor in comparison to the young?

Is there any chance this can be turned up some please? I always wondered why nobody was in there hunting, and why young was always so crammed, but I'm starting to see why.

A bit of a spawn rate increase would go a long way to making these great! Thank you!

Interesting, thanks for the heads up. I'll shuffle over to the waterfall and see how that goes, hopefully get a bit more action and none of the downtime I've been seeing
