You need testosterone for antlers to harden, once testosterone levels reside antlers start growing again.
He has a nut some where for the antlers to harden.
I killed a few stag Whitetails that where hard horned up top but bases where still soft. Just means had a little bit more testosterone then thier velvet all year counter part
The deer in our county (matagorda) are usually out of velvet in late August. This one still had some hanging at end of October. So clearly something is off with hime. Think he will be bigger next year?
