I can say that not all hostas are equally loved by the local deer. For the past 2 years, they ate my June and Paul's Glory and Blue Cadets right to the ground. But they never even nibbled on the big Blue Angels or Sum&Substance.
So early this year as they were just emerging, I dug up all the deer candy and moved them into the fenced back yard where the deer have never jumped, and divided the 3 Blue Angels into 13 pieces and replanted them to cover the entire former various hosta beds. They are thriving.
The deer have been around (they pulled up a few newly-planted astilbes but did not eat them and I merely replanted them). But they have not so much as nibbled a Blue Angel.
I don't think that is just good luck.
