They usually shed in late winter. Late Jan. or early Feb. in my area. They start growing new antlers in the spring, growing them through the summer. They harden in the fall.
Yes. They are shed in late winter to early spring. The deer grow a new pair during spring/summer and they are ready for “rutting season” during the fall.
@snowberry That’s not what happens, and your link doesn’t say that it does. Your link indicates that deer shed their antlers, which is true. However, it does not say that they do so in the summer (which was the question), because they don’t.
@filmfann no, most antlers are eaten by animals for the minerals that are in the antlers. But you shouldn’t be upset if you do. Finding a matched pair of antlers can earn you some decent cash from a taxidermist.
