She'll be 5 in February, if I remember right.
This horn fell off on its own - it folded backwards, then got all wiggly and detatched. Her other horn she managed to damage a couple weeks ago butting another doe and it bled for a couple hours, but it didn't seem to help it come off (obviously as it's still on there).
Scurs are trickier to band, I think. Worth a try though. PM me if you'd like, I'd rather not get into details here. I have a buck with flat scurs (no more than 1" tall, crecent shaped). He rubs his scurs off on the fence all the time, and they leave an oozy stump that I have to treat with antibiotic ointment. The man that taught me to disbud said I could try to burn the stumps with the calf tip of my iron...but that it might not work, so I decided not to try it.
