It’s common for bucks that are healthy to hold their antlers until mid March or so. There’s so much ag in eastern Kansas that I suspect the bucks are very healthy in your area.
Bucks, does, and fawns will use licking branches (the branches overhanging scrapes) year round. In addition, female fawns often become receptive when they reach about 70 pounds. There are probably some receptive fawns causing bucks to display rut behavior in your area.
After the majority of rutting behavior is over and the testosterone level of bucks begins to decrease they often get together in bachelor groups and will remain in these groups till they begin shedding their velvet next fall.
