Welcome Nate - I know that for us farmers it is very difficult to ''cut off'' the very element that we've waited all year long for our bucks to grow...the very element that ''trips our trigger''! But, I strongly recommend that you cut them off. In the long run, you'll be glad you did. One has to come to a place in your 'love of the antler' to be satisfied watching them grow all summer, then enjoying them in hard horn for 4-6 weeks, and call it good.
You've been given a wide spectrum of truth in all the previous posts.
Like Jeff says, some bucks are not aggressive enough to worry about(I have one), but, how many does will you lose finding this out, and what if the ''non aggressive buck'' has a bad day?
And yes, bigger pens help alot, but unless you build them round, 'bigger pens' still have corners in them.
Like Mike said, and so many others will tell you, when you lose a deer, it's always gonna be one of your best...or your best! And yes, the deer you lose could easily be the ''one'' that takes you to a new level. Most successful deer farmers have that ''one'' special deer that did in fact launch them into their success.
Hunters Dream - I've never seen a problem with them losing those nubs no matter how close I cut, but I don't think it hurts to leave an inch or so. Sounds like Gary has though.
Nate, it's all about Murphy's Law. I think that ''law'' was enacted by and for the deer farmers of the world. ''What can go wrong WILL go wrong''. And sometimes things that can't go wrong, go wrong! So...why take unnecessary chances?!
Stepheck - I think you put it best...''Better to 'cut' than to 'dig'!
