Still have antlers
I pulled the cards from my trail cameras on Sunday and in addition to antlerless deer, there was a portrait of a nine point looking right into the camera. The date was March 9th.
A friend who has a deer farm told me years ago that he had bucks hold onto their antlers into April; drop them; then start their new set within a week or two. But I never saw them that late in the wild.
The poster formally known as Duncsdad
Everything I say can be fully substantiated by my own opinion.
