Yuck...
Sounds sick....
If it was injured, I'd totally have put it in the freezer.... Sick downed critters aren't safe to eat...
I don't know about Texas, but in these parts.... Deer populations have skyrocketed due to cutovers and constant urban expansion....
It's sad, but they're pests, and nothing is thinning the herds...
I used to garden in a neighborhood where I'd stop and count the numbers in the herd.... 30 or so.... There was even a 3 legged deer!
Do you know what you can grow in that kind of situation?
Hint... Dig out anything with bite marks...
