I might shoot em both, hard to tell what I'm going to to when somebody hands me a gun! Seriously though I think if you are trying to grow big bucks you should let him go and see what happens. If you let him go he may turn into a nice buck, if you shoot him he will just die.
maybe i'll phrase my question differently. if i see him this year, i wouldn't shoot him anyways because he's a little guy. i've got a way bigger doe problem than antler genetics (which is a huge misconception).
i was really wondering, is he always going to be a unicorn? he's been on several of my cameras for months, so I'm pretty certain he's never had two. a cull deer at 3.5 or 1.5 is still a cull deer in my eyes.
Way too early for anyone to say he will always be "this" or "that". Give him a chance and see what happens. Like one guy said, all you can know is that at this point if you kill him he won't get any bigger - that I will guarantee .
