yep, they shed them every year and then grow them back come next year. And usually as the buck matures they get bigger every year. And when the new ones come they have velvet on them to protect the new growing antlers until they are good and ready. then the deer rub the velvet off on trees and shrubs and things. Mice and other critters will eat the sheds for calcium and other minerals. Antlers are genetic too im pretty sure.... so if daddy has a goofy rack or a drop tine, the son will most likely develope one too. I think thats where the term "management bucks" come into play when ur watching hunting shows on tv you will here them say that and those ar the bucks they are after to better the quality of their heard so that deer doesnt pass on those genes anymore. Does that answer your question? hope it helps!
