SJ,
Do you mean the killing part? or the gutting part?
He killed his first deer when he was 5 years old, almost 6, it was a couple weeks before his birthday. But he had watched me skin a deer the year before.
When he was watching me skin a deer, my hunting buddy, looked over at him then back at me and said " Has he ever seen this before?" I told him no, but he had to start sometime, and there were no ill effects from that. But he didn't get right up to us.
He did start referring to the skinning shed as the "Blood Barn" after that though.
Right before I took him on his first deer hunt where he was going to be shooting a deer. My wife asked if I was going to traumatize our son when he killed a deer? I hadn't really thought about it until that point and I worried about it the whole time. If I could post the video of that hunt and his after the hunt commentary as he was kneeling over the deer, you can see that it didn't bother him at all.
I think they pick up on our attitudes and feelings about things like that as much as they have their own notions about it. I act like it is a normal thing and he does too, and he hasn't been the least bit squeamish. Now his mother wants nothing to do with it and leaves the room when we talk about it. I did have to explain to him this past weekend he could not cut the hooves off and take them home. He wanted them for his "collection". His mother would have flipped out!
But now in all fairness, we don't technically gut deer in our neck of the woods these days. We roll out the backstraps, round off the shoulders, debone the hams, and roll the gut sack down far enough to remove the inside loins. So he has never watched anyone gut a deer the way I was taught when I started out. But he did help me this time by holding the hide, pulling on it and putting meat in the cooler. Next time I'll let him do a little more and when he's big enough, I'll let him do all his and mine too
Bob.
