last years fawns can still come in through March. My theory is if your doe to buck ratio is to high then the bucks cannot keep up causing you to still have does coming into heat through march keeping the bucks testosterone levels high and therefore making them hold onto there antlers longer. I raise deer and also know that some guys take away there protein in february and this usually causes them to drop(of course this is what they claim caused them to drop) Anyway just my two cents haven't seen an antlered buck since first week of march.
