Seeing 3-4 spikes a year is not uncommon on my place but I've seen over a dozen this year and seeing the same on the big ranch. Buddy has a place nth of town and he's reporting the same thing. We've had a mild green summer with plenty of rain.
Seven years ago we where in a drought, we now have a very healthy 4 and 5 year old doe herd. Older healthy does (mild winters and decent summer rains) means more twins more fawn recruitment
Does that suggest that the weaker fawns that normally don't survive are spikes and since we have such favorable conditions is the reason they are alive?
Could, But I wouldn’t over think it or even try to hypothesis that’s the case with unknow variables. Weak antler growth could be a production of the environment 18 months after they are born. Define favorable conditions? Mild but very dry winter? Is that March Rain? Aug rain?
Population spikes all start with healthy doe crop that’s mature, and in premium shape at conception. It’s the First thing it takes for a a high fawn recruitment year.
Simplest and most confirmable anwser, more fawn recruitment
