Feeding spruce to rabbits

We regularly feed broadleaf tree branches to our rabbits, usually aspen or willow. Does anyone have experience with feeding spruce boughs to rabbits?  Google seems to be conflicted on this topic so I'm looking for someone with experience

When I had pet rabbits, they would chew on spruce sticks with no issue. I tend to find spruce tree damage from rabbits only from hard winters. They tend to prefer my young fruit trees it seems!

When feeding my rabbits branches or bark chews in the winter, I do feed some spruce and pine in moderation, while being mindful of when I read briefly about pine induced abortion in cattle.  I admittedly didn't read deep into the studies regarding the specific species of evergreen or whether it can occur in other animals.  I don't breed my rabbits in the winter months anyway and have never noticed any side effects from feeding spruce boughs.  By the time I start breeding in springtime (Maine z5), other trees are budding.

According to Bunnymeadow spruce is safe.
