I have watched them over the years that were missing either a front or back leg and one was here for three or four years. She was missing a hind leg but had two fawns every year. We did feed her every winter.
I was thinking it would take a compound fracture or getting caught on a fence, something to break the skin, wouldn't have thought of that.Could be anything. Most likely a joint injury from doing deer things and it fell off over time. We have a buck we have been watching for 4 years that had an injury and last year the leg fell off at the joint.
I think over time they will atrophy away as blood flow decreases. I have tons of pictures of this buck. In 2016, 2017 and most of 2018 he had his leg tucked and it kept getting smaller. By October 2018 it was dangling down and gone in Dec 2018.I was thinking it would take a compound fracture or getting caught on a fence, something to break the skin, wouldn't have thought of that.
She probably couldn't outrun the bucks anymore MZ!We had a doe years ago that only had three legs. She was such a good breeder she was off limits to shoot. I don't remember how old she was or remember how many years she was on our cameras but think she died of natural causes.
