By the way I understand it there is an antler growing as soon as they drop them.

The timing of antler casting also is important. Research has revealed that both nutrition and dominance rank can influence when a particular buck will cast its antlers. For example, Michigan researcher John Ozoga noted that providing supplemental feed to bucks delayed their average antler casting date by more than a month from late December to mid February, with some bucks even carrying antlers into March. Likewise, bucks under extreme nutritional stress will cast their antlers early, some even before the end of hunting season. This situation is particularly common in eastern hardwood forests that rely on annual acorn crops. In years of widespread acorn failures, bucks often shed their antlers several weeks earlier than normal. Nutritional stress also can result from extreme or prolonged rutting activity, especially if the buck did not enter the rut in prime physical condition or if he had inadequate nutrition immediately following the rut.
Researchers also have documented that the interaction between a buck’s dominance rank and the length of the breeding season can affect timing of antler casting. In general, a buck’s dominance rank is affected by age, body weight and testosterone levels – all of which typically increase with age, at least until 5 _ years.

the pedicels will scab over and heal. it could be several months before they begin to grow new antlers.
