Ok, I do have a fawn in the area. Spots are almost gone. Maybe she is an old nanny drawn down from nursing. That photo just had me wondering. After looking back at other photos I think you guys are spot on. I just didn't put 2 and 2 together. I'm still new at all this.
I agree, she's pretty old. Older does tend to lose that sleek/smooth appearance and being to look more lumpy. Hip bones stick out more, stuff sags.
That said, I had a couple that were sick last year, and they didn't look far off from the condition of that deer. Ribs begin to show heavily, and that pocket in front of the hams gets deeper and deeper.
IMO, she looks like she might have been sick and is on the mend. But her coat and her general carriage (from the few pictures you provided) seem fine and if I had to guess she's just older or has been nursing.
