Being new to Texas I wasn't familiar with melanistic deer; pretty darn interesting!
Found this: The odd "black" deer has shown up here and there, from the East Coast to the Great Lakes to the northern Rockies. In fact, below you'll find a photo of a striking melanistic 8-pointer shot in southeastern Pennsylvania in 2002. But it's safe to say that at any given time, there are now more melanistic whitetails alive in Central Texas than in every other part of the planet combined. Melanism is actually fairly common in all or parts of eight counties: Hays, Travis, Comal, Williamson, Blanco, Guadalupe, Burnet and Caldwell.
I think you ought to leave her be and let her finish out her life and just enjoy seeing her if you get the chance. Besides, as poor as she is......it looks like she's knocking on death's door anyway.
That's a gran-matriarch doe. Her poor condition may take her out before season gets rolling... but that old girl has EARNED A TIP-O-THE-HAT (honestly, no telling how many great bucks she's fawned), not a broadhead.
