She's definitely thin and mature. Look at the long nose on here. Hard to estimate age but most does are older than we really think they are comparably to bucks. Perhaps she's just a real old mooley, let's hope and I'd put her on the hit list. Got doe tags?
Either she just moved in from a very poor area, was sick or she is so old her teeth are gone (or close to it). I'm thinking its that there are virtually no teeth left. I hope you get her this year.
Germ, If you get her have her aged. It would be interesting to know her age. She looks like a Old Girl to me.
