Well I grew up hunting in all forested area lands, zero farm for 25 or more miles away, and had bucks in april with antlers on, so I don't think where they li e at matters
I've come to the , antlers come off more based on when they started growing, as if a buck was born early in may or june, there antlers just start growing sooner,, thus fall off sooner
the farm I am on, I can deer shed antlers in mid dec, and some will hold them till late march, all same herd deer, with same food supply

tonight in my back yard I had two small bucks show up with half racks on, other side shed, so there dropping now it seems, might be a good time to go for a walk and look
