do reindeer shed their antlers

Yes, reindeer shed their antlers as part of their natural biological cycle. Reindeer shed their antlers every year, usually during the spring and summer months. This process is known as "antler casting" or "antler drop". As the antlers shed, new antlers begin to grow in their place, providing the deer with a fresh set of antlers for the following winter season. Reindeer are one of the few species of deer that shed their antlers, as most other deer species retain their antlers for life.
