Deer occasionally can contract rabies, also deer with CWD act very strange as well but she seemed way to coordinated to me for that.
I think the thing got triggered and decided to deal with the threat of a predator like most animals do when their young are involved, it’s the length of the attack that surprised me, she never let up even after the threat was removed.
Yes, that deer was very persistent.
She stomped that sucker flat.
