Well I think it depends on the actual individual, ok example first time mothers have 33.3% chance of having a stillborn , perhaps monitoring the mothers closely will help a successful delivery. However you might want to replicate a wild birth, where all the herd takes part. But that usually consists of experinced mothers who know what to do, take example the emmen herd.
Where as a group of juviniles might panick and react badly, e.g trample then baby, or even kill it intentionaly.
